Ok, my fist post didn't have good examples to show what I was pointing out.

Consider a case like this where the three snippets produce the same output:

Traditional my way:

my $n; for (1..5) { $n++; say $n }

__END__
Prints:
1
2
3
4
5

New state way:

for (1..5) { state $n++; say $n }

__END__
Prints:
1
2
3
4
5

I just was wondering if the fact of declaring the variable inside the loop has an extra cost compared to declaring the variable first out of the loop. But it seems like there is no difference in time cost as far as I could test anyway.
