I'm not quite sure who said "don't tracktrack past this point" or even "don't backtrack past this point"? I know it wasn't me:)
That leaves me with the same dilema though. What does x<0> mean?
Does asking to match something exactly zero times mean:
- Don't do anything?
- Or: Don't accept an x here.
- Or something else which I haven't underdstood?
I'm only just getting to grips with Perl5 regexs, and have only used the 'simple' ones so far, but the idea of instructing the regex engine to match something zero times seems nonsensical to me at this stage. Unless it means "Fail if there is an x here", but that would be the same as [^x] or -[x] (or is that -<x>) in the new money?
What's this about a "crooked mitre"? I'm good at woodwork!
