How 'bout this one. (I mean to bring it up on perl6-langage or somewhere, but I haven't done my homework yet, so I'll float it here.)
A6 says that, as in Perl 5, only anonymous subs are closures. I've always thought of the fact that Perl 5 named subs are not closures as a bug kept for compatibility.
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.
