Thanks for that. I only recently discovered lookaheads when I was writing the syntax definition for the sublime package, and found them extremely useful. This entry will hopefully help more people notice them sooner.

Of course you can't start to explain all the Lookaround functionality, but I think it might be nice if you included that you can also do a negative lookahead with (?!something) somewhere in there.
