petdance,
I freely admit I have never used possessive quantifiers nor can I think of an example where I might want to. I was skeptical by your statement that perlre didn't have an example so I looked: For instance, the typical "match a double-quoted string" problem can be most efficiently performed when written as: /"(?:[^"\\]++|\\.)*+"/...

It goes on to say that it is just syntactic sugar and could be re-written as /"(?>(?:(?>[^"\\]+)|\\.)*)"/

Cheers - L~R
