"Better use foreach instead of for, when you iterate over an array."

Why, they do the exact same thing:

print $_ for qw(foo bar baz);
print $_ foreach qw(foo bar baz);

$ perl -MO=Deparse foo.pl
foreach $_ ('foo', 'bar', 'baz') {
    print $_;
}
foreach $_ ('foo', 'bar', 'baz') {
    print $_;
}
foo.pl syntax OK

I will admit that i tend to use foreach when i iterate over a 'collection', but never hardly ever (never say never...) when iterating over arrays. As a matter of fact, i have really started to favor for over foreach because foreach is just too wordy. But, consitency is alway king. :)
