    I think we are getting close to the final version. Good job! Still though have two higher level comments:
    
    - is current times().greedy() behaviour intended? For pattern `a{2, 5} b` and sequence `a1 a2 a3 a4 b` shouldn't it return just one match: `a1 a2 a3 a4 b` Instead of three as in `testGreedyTimesRange`
    - this feature should be documented in the docs. It should be also very clearly stated there that it does not work for `GroupPatterns`
