( #3333=superdoc: print w/ replies, xml ) Need Help??
I get strange results from a slight variation:
use strict; use warnings; my $i = 6; sub my_print { print $i; }; for ($i = 1; $i < 3; $i++) { my_print(); print " (C-Style:\$i==$i)\n"; } for $i (qw|x y|) { my_print(); print " (Perl Style:\$i==$i)\n"; }
Output:
1 (C-Style:$i==1) 2 (C-Style:$i==2) 3 (Perl Style:$i==x) 3 (Perl Style:$i==y)
Not that I would write code like this, but how come the "perl style" does not update the "$i" the sub sees ?

             Most people believe that if it ain't broke, don't fix it.
        Engineers believe that if it ain't broke, it doesn't have enough features yet.
