Wasn't a demand for respect, just making a point about serious applications
and the languages used for them. Games arn't serious.

Your definition of "serious applications" seems to coincide pretty
substantially with "fields I, personally, have worked in," particularly
since you've conveniently ignored the passel of non-game applications
that have also been cited in order to focus on the one you feel most
prepared to trivialize and discount in pursuance of your "argument."
And in addition to habitually slagging on applications and tools you
don't consider "serious" for no particular reason and with zero
provocation, you name-call like a grade-schooler. So it's difficult
*not* to parse your overall behavior as simian chest-thumping and

conveniently set by yourself.

Case in point. But for the sake of argument, let's review:

Person: "This thing exists."
Muttley: "Nobody uses that."
People: "Here's all these things that use that."
Muttley: "Those don't count."
People: "Come again?"
Muttley: "They're not serious."
People: "What's your definition of 'serious' here?"
Muttley: "Things that I've worked on."
People: "...Um."
Muttley: "Also you're a poopiehead."

Redefinitions *stack,* too, so "foo" can mean multiple completely
different things in different contexts depending on which definition
was current at the time.

: foo 2 * ;
: double foo ;
3 foo .

: foo 1 + ;
3 foo .
3 double .

Genuine Forth-heads do staggering things (implementing OOP, etc.) with
this; personally, it gives *me* the willies.

That's why mastering Forth takes a lot longer than just learning the
language!

I think that when finding the definition of a word, Forth just searches
back through the stack of definitions until it gets a hit. And if that
word definition uses other non-primitive words, it goes backwards from
where it currently is, looking only at definitions from before the
current word was defined. Is that right? And if so, can you do
"forward declarations", and mutual recursion somehow?

(I guess this is getting way off-topic for comp.unix.shell, and pretty
questionable for comp.unix.programmer - I don't know how much the
regulars there try to stay on-topic, or if they like threads like this.
I'll happily remove those groups from posts if there is objection to it,
but I don't want to cut out people who are interested if they want the
posts there.)

That's my understanding, yes; essentially, it's a consequence of the
fact that definitions are stored as a list of pointers, and re-
definitions are simply appended to the dictionary without going back
through the rest of it to update any pointers to the prior definition.
A strange design choice, but they're consistent with it.

Forward declarations are possible using the CREATE ... DOES> construct,
which creates a definition that invokes a function pointer which can be
changed later. I dunno about mutual recursion, but it wouldn't shock me
if the same trick could be applied for that.

(And yes, if we ought to pare this back to comp.lang.misc we certainly
can.)

It's explained reasonably well at the top of the "perldoc perlclass"
documentation in Perl 5.38:

History
Since Perl 5, support for objects revolved around the concept of
*blessing* references with a package name. Such reference could then be
used to call subroutines from the package it was blessed with (or any of
its parents). This system, while bare-bones, was flexible enough to
allow creation of multiple more advanced, community-driven systems for
object orientation.

Class feature is a core implementation of class syntax which is familiar
to what one would find in other programming languages. It isn't a
"bless" wrapper, but a completely new system built right into the perl
interpreter.

It says there is already supposed to be a mechanism for this, it doesn’t

I don't know at all whether Forth does this or not, but this design
choice allows the list to be restored to a prior state, whereby the
recent definitions are forgotten, and the old ones revealed again,
similarly to shadowed lexicals being revealed again upon the terminaton
of an inner scope.

It sounds reminiscent of the assoc list representation of the lexical
environment in a rudimentary Lisp interpreter.

There are plenty of fields I haven't worked in that I would also consider

I suppose it also makes it a great deal easier to have small local
functions. Forth programming, as I understand it (I've only done very
small tests in Forth - I've never written a "real" program) generally
involves breaking code down into very small pieces. So your
implementation of "foo" might involve defining words like "get_next",
"double", "set_x", or whatever. (In Forth style these would probably be
shorter names, and perhaps include symbols.) Your implementation of
"bar" might want to re-use these same names but with different
definitions. With the list of pointers design of Forth, you can just
redefine these "local" words as you need to, and ignore any previous
definitions.

"word" in Forth terminology is more like "function" in common imperative
languages. (It is not exactly the same, since Forth "words" are much
more flexible - that is both a good thing and a bad thing.)

There's a mechanism for method dispatch in class hierarcies. There's no
builtin support whatsoever for handling class instance data (or class
data, for that matter). This has certain advantages (everything a
reference refers to can be used as object, eg, file handles) and is
reasonably easy to provide for cases without multiple inheritance and
doable otherwise. OTOH, that absolutely not what people familiar with
other programming languages expect and also beyond what many of them can
wisely handle. Hence, a more dictatorial approach is probably expected
to improve things¹.

¹ Somewhat questionable when looking at another newer feature, namely,
subroutine signatures. It would be absolutely great if perl support real
function prototypes including checking function invocations for
correctness at compile time *and* *not* at runtime everytime a
function is called.

Very well, then! That leaves us with the larger questions:

* By what logic do you argue that a language which is commonly used in
fields which are (by your own admission) "pretty big" but (in your
assessment) not "serious" is therefore "pretty irrelevant in most
language discussions?"

Are none of these "serious" by your standards?

On the contrary, you've been the one dragging it down from the start;
the first to name-call, the first to accuse someone of being a sock-
puppet, the first to mock other people for having specialties you don't
consider "serious" - and, for that matter, the person who started this
off by talking pointless smack, as if anybody in comp.lang.misc cares
whether a language is considered "relevant" or "serious."

I am no Minecraft expert. You might need an add-on, or special mode, or

The amount of code written in the language. I doubt game scripting amounts
to much in the scheme of things.

Don't remember them tbh. A serious application IMO is something that
impacts society as a whole in that if it didn't exist we'd be in trouble
or something that benefits a persons ability to live their life.
If games vanishes some teenagers and kidults might get a bit annoyed for
a while before they went outside and played with a ball but society would
carry on as before.

Its a very relevant insult given these days every socially awkward moron
decides they're on the spectrum so they can have some kind of disadvantage
kudos.
