[issue12870] Regex object should have introspection methods

[Ezio Melotti]

Ezio Melotti <ezio.melotti at gmail.com> added the comment:

These additions sounds more useful as an external tool than regex functions/methods.  There are already a few tools able to "explain" what a regex matches.
The use cases you proposed are too specific to deserve new methods, and using them programmatically sounds like premature optimization IMHO.
