in reply to alternation in regexes: to use or to avoid?

Trying to sound knowledgeable without knowing why or how you got the results you did, I would suspect that this is something that you can't rely on in every version of Perl, and possibly even system to system.

A Monk aims to give answers to those who have none, and to learn from those who know more.

    Right, forgot that ... I tried it on 5.10, 5.16, and 5.17.6, with almost identical results. As to a system, I really doubt that it matters.
