Re^3: Simple Regex drives me insane

It already does do that.

Specifically, it always matches, setting $1 to foo if #\w+ is found at the start of the string, and setting $1 to undef otherwise.

That said, I believe it has other problems. It doesn't set `$1` to `foo` when matching against `bli #foo bla`. It doesn't set `$1` to the empty string when matching against `bli bla`. However, it does set it to undef, which might be close enough.	[reply] [d/l] [select]
