I'm not sure what you mean about for() copying an array before iterating.
That is certainly not the case. In fact, the iterator variable is aliased
to each element of the array in turn, and modifying the iterator variable
modifies the element in the original array. For example:
#!perl
my @array = (qw/tsuJ rehtona lreP rekcah/);
for my $word (@array) {
$word = reverse $word;
}
print "@array,\n";
