"Inside STL: The shared_ptr constructor and enable_shared_from_this" by
Raymond Chen

"If you create a class of the form"

struct S : std::enable_shared_from_this<S>
{ /* ... */
};

"which derives from std::enable_shared_from_this of itself (using the
curiously recurring template pattern), then this class becomes a
candidate for special treatment by shared_ptr: The shared_from_this()
method will produce a shared_ptr<S>. Some restrictions apply."
