Is a dictionary the good container or should another class be used? Because in the example the content of the "verse" group is lost, excluding its sub-groups. Something like a hierarchic MatchObject could provide access to both information, the sub-groups and the group itself. Also, should it be limited to named groups?
I am wondering what would be the best direction to take this project in.
Firstly is it, (or can it be made) useful enough to be included in the python stdlib? (ie. Should I bother writing a PEP for it.)
And if so, would it be best to merge its functionality in with the re library, or to leave it as a separate module?
And, also are there any suggestions/criticisms on the library itself?
I find the feature very interesting, but being used to live without it, I have difficulty evaluating its usefulness. However, it reminds me how much at first I found strange that only the last match was kept, so I think, FWIW, that on a purist point of vue the functionality would make sense in the stdlib in some way or another.
