Hello everyone!

I have the following regexp:

(?P<question>.+(?<!\[\[))

It is designed to match hello world! in the string hello world! [[A string typically used in programming examples]]

Yet I just matches the whole string, and I can't figure out why. I've tried all flavors of lookaround, but it just won't work...

Anyone knows how to fix this problem?

Thanks,
CFP.

There are some features in modern regex engines which allow you to match languages that couldn't be matched without that feature.
