You'd need to have declared $ret as a global somewhere for local to localize it. Remember that local() declares nothing.

use vars '$ret';
sub regex {
    local $ret = '';

What you didn't realize was that the (?{ ... }) is a closure so when it first ran it captured the original $ret and continued to write to that same instance which wasn't the same one being returned in later iterations.
