in perl's "apocalypses" on pattern matching[0] (I.e. perl6 regexp design documents) Larry Wall immediately states that /x should be the default (and not be an option at all!) for regexes.

It's incredible how useful it is and yet by not being the default every regex implementation has nudged their users to write inscrutable regular expressions for decades.

I must give Perl 6 another look, I was using 5 up until about 2009 when I replaced it with Ruby. Be nice to see what's been done in that time.


Please note that Perl 6 has been renamed to Raku (https://raku.org using the #rakulang tag on social media).
