Looking over some code I saw
my $text;
for $text(@array){
$hash->{$text}++}
"That won't work," I thought. "It should be:"
my $text;
foreach $text(@array){
$hash->{$text}++}
But investigation showed that it worked fine. Further,
my @foo = qw(bar baz ne);
foreach (my $ix=0;$ix < @foo; $ix++){print $foo[$ix]}
printed out
barbazne.
So it looks like for and foreach will accept each others' formats. Are they in fact equivalent? Or is code that exploits this vulnerable to subtle bugs?
thanks
