> I'm more-or-less waiting for the "blank" in: "blank" is to Python what Regex is to Perl.

This will sound like a forced joke but I genuinely didn't understand your phrase. I got stuck re-reading several times the "blank" in: "blank" part, but my mental language regex wasn't matching the expression.

I think the bug is caused by a bogus quote that causes a bad parameter expansion. My regex engine parses this better: the "blank" in: "blank is to Python what Regex is to Perl"

Off by one errors...
