Re: Static variables (and also Perl 6)

Some have tried to explain why static variables are good. I understand it's needed to preserve state, but what's so wrong about the closures we're using right now? ({ my $foo = 3; sub { ... } }) Maybe some filter can provide some syntactic sugar, because that's what this seems to be all about.

I haven't seen Tie::Static in this discussion yet - is tie not good enough?

Update - Putting money where mouth is - I created a filter :)
Filter::Static

Note that with Perl 6 we can use := to do what I did with a tie, resulting in the same idea but without most of the overhead.	[reply]

but what's so wrong about the closures we're using right now? ({ my $foo = 3; sub { ... } }) What's wrong with them indeed? I've seen several references above to needing the my's allocating behavor to be BEGIN{}ed, but I don't see the reasoning behind it. I've used this behavor fairly often when I want an iterator expressed as a counting and a reset function. `TACCTGTTTGAGTGTAACAATCATTCGCTCGGTGTATCCATCTTTG ACACAATGAATCTTTGACTCGAACAATCGTTCGGTCGCTCCGACGC`	[reply]
