Since it has been suggested that you use strict and avoid symbolic references, the inevitable question will be "then how do I do what I'm trying to do here?" The answer is almost always to use a hash. Here's a quick example of your code ported to use a lexically scoped hash:

my $n = 0;

my %nums;
foreach ( qw( zero one two three ) ) {
    $nums{$_} = $n++ || "zero";
}
my $msg = "";
foreach ( qw( zero one two three ) ) {
    $msg .= "$_ = '$nums{$_}'\n";
}
print $msg;

print qq(
zero = '$nums{zero}'
one = '$nums{one}'
two = '$nums{two}'
three = '$nums{three}'
);

You get the benefit of being able to dynamically create entries in the hash, without the side-effect of possibly clobbering unrelated variables.
