Re^4: Regex: Capturing and optionally replacing

Okay... this one kept me awake last night :(

Because I'd still like to know... how could I have re-written the original expression to get rid of the unwanted commas?

Can somebody please put me out of my misery?
(I promise I won't use it in production :D)

Substitutions work by editing the string being matched, but you want the substitutions to work on the string being returned. That doesn't work. You could do it with a parser, but Perl 5 regexp are not good enough to form a parser. (Well, it's theoretically possible with experimental regexp features.)	[reply]
