Well... there's always the issue that closures are done by instantiating the sub at runtime, while named subs are instantiated at compile time, which causes some difficulties. (As the enclosing sub's lexicals instantiate at runtime, thus giving the contained sub nothing to close over)
Now, if the named lexically scoped sub actually got re-instantiated every time, *that* would be different.
YES. That's what we want. That is how Scheme and Common Lisp work. That would make for cleaner code.
Well, if that's what you want... :)
I'm OK with that. Convince Larry and I'll make it happen.
