This is a bug report for perl from perl@profvince.com,
generated with the help of perlbug 1.39 running under perl 5.10.1.
-----------------------------------------------------------------
[Please describe your issue here]
Perl doesn't reset the array iterator when the array is cleared :
$ perl5.12.1-64 -M5.012 -E 'my @a = "a" .. "c"; my ($i, $v) = each @a; say "$i: $v"; @a = "A" .. "C"; ($i, $v) = each @a; say "$i: $v"'
0: a
1: B
The issue is still present in 5.13.1.
Vincent.
