Actually, I consider this a good thing. There are lots of times when
I would LIKE my loop variable to persist and, in order to get that, I
need to do the following:
my $n;
for ($n=0; $n<10; ++$n) {...}
...do stuff with $n...
It's a minor ugliness, but it itches at me. Under the new Perl6
rules, I can easily have it either way.
{for (my $n=0; $n<10; ++$n) {...}} # Local to loop
for (my $n=0; $n<10; ++$n) {...} # Persistent
--Dks
