#!/usr/bin/perl
@list=qw(one two three);
foreach(reverse @list) {
print “$_\n”;
$_=”foo”;
}
print “$list[0]\n”;
Finally it will pring ‘foo’ not ‘one’. Because
$_ isn’t a copy of the list element, it’s a reference. Modifying it will change the list.
$_ will hold the reference, not the copy of variable
