in reply to smart match operator should be smarter!

1. This is your untouched code and my results:
use strict; use warnings; use 5.010; my @numbers = (2); my @other = (2); if (@numbers ~~ @other) { say 'yes' }else{ say 'no'; } #output: yes if (@numbers ~~ (2)) { say 'yes' }else{ say 'no'; } #output: yes

2. This is my perl -v:

This is perl, v5.10.0 built for i486-linux-gnu-thread-multi

3. Could you post here the output of your perl -v?

    ikegami said earlier that the smart operator was changed after version 5.10.0. Apparently, it was buggy and too unwieldy to work with. As a result, it is no longer commutative.

    $ perl -v
