I have a menu like this:

menu .m -tearoff false
.m add radiobutton -label 2 -value 2
.m add radiobutton -label foo -value foo

.m entrycget 0 -value
2
.m entrycget 1 -value
foo

Now

.m entryconfigure 2 -value two

fails to configure the first menu entry, since the "2" is taken as
numerical index, and thus the last entry is configured instead:

% .m entrycget 0 -value
2
% .m entrycget 1 -value
two

Is there some way to "configure-by-numerical-label" other than iterating
over the menu and checking whether the label matches the desired value?

The index for menus follow the rules for [string match]; as it does various forms of matching (including wildcard), you can use \ to indicate a literal character. So if you use {\2} for your index, it doesn't get treated as a numerical index and instead looks for a label matching the literal character "2".

..m entrycget {\2} -value

Mike,
great, exactly what I am looking for! And since this is documented
behaviour, it is not even a 'hack' :-)
