Re^2: zero-length match increments pos() (saner)

I completely disagree. If a regex engine fails to find the zero width match at the end of a string then it is broken.

Note the correct way to refer to capture variables in the RHS is $1 etc, not \1.

It already found a match at the end of the string. It should not find two different matches at the end of the string. If I'd used $1 then I would have gotten `x$1cx$1cx$1cx$1` [download] because it was vi, which isn't Perl (because otherwise it would have not been a good choice for demonstrating how it doesn't act like Perl). - tye	[reply] [d/l]
