Hi Richard and Christian, thanks for the comments/suggestions.
For the "self species ofSize… », I got inspiration from the image like with #overlappingPairsCollect: As for float rounding errors, that interesting to consider indeed. I’ll try a buffer variant. Some related questions for my OO culture ;-) : #average is defined in Collection… That makes me wonder (especially in Collection hierarchy) that some methods are not applicable to some subclass. I think this is a common problem with inheritance ? What’s the way to deal with that ? Traits ? I found #shouldNotImplement that is used 106 times in one P8 image. Is it a good/favored pattern to prevent usage of such methods ? Cheers, Cédrick PS: would such method be a candidate for integration in base image ? If yes, I could try a PR.
