I always knew the whole AI thing is scam. Description this bot generated was pathetic. "Optimized" regex captures till end of line:

>perl -wE "q(a@) =~ /((?:(?:[^\n@]+|@[^@]*@)\n?)+)/; say $1"
a

>perl -wE "q(a@) =~ /((?:(?:[^\n@]|@[^@]*@)[^\n]*\n?)+)/; say $1"
a@

Making second star modifier non-greedy makes the expression even less optimal. So what's "pretty good"?
