The Pörl community actually made me laugh :) . That last comment about asking all of this because I'm lazy wasn't supposed to be taken seriously. If that was really a concern for me I'd write in Python, not Perl. And switching from AZERTY to QWERTY is done easily enough. I do see where the joke went wrong though, it's not obvious that the [ and ] characters are actually extremely simple to type, and just require to hold one key while pressing the other. I should have thought this through.
My point with this meditation was actually about the unexpected behaviour that parenthesis may lead to in regexes. The only simple is example I could think about was the use of split, but I wondered if it couldn't have other repercussions.
