Should a regex compile if a group is referenced before it's defined?
Consider this:
(?:(?(2)(a)|(b))+
Other regex implementations permit forward references to groups.
BTW, I had a look at the re module, found it too difficult, and so started on my own implementation of the matching engine (available on PyPI). |
