Re: Isn't Perl5 ready for C<my sub>?

The perl5 parser has had a placeholder for lexical subs for quite a while:

$ perl -we 'my sub foo {}'
"my sub" not yet implemented at -e line 1.
$
[download]

and a pad can quite happily accomodate them.
The main things holding them up has been trying to agree their semantics, then someone - probably me - finding the time to implement them :-(.

Let me guess... since in Perl5 an assignment to the declaration of a lexical variable can't contain the same lexical variable in the rhs (well, poor phrasing, but no doubt it's clear what I mean!) there's not yet full consensus on what should the name of such a sub refer to within its own body. Got it?	[reply]

well, that's one thing. Then there's things like: does the sub get re-created on each scope entry (so it captures external lexical vars anew) and does it affect method resolution? Dave.	[reply]
