I’m not as easily convinced, I think sticking to lists:zip is preferred over introducing new syntax.
Also in the light of EEP 70: Non-filtering generators this proposal needs a complete overhaul - so perhaps better to postpone the discussion until that is done!? I look forward to seeing all cases covered such that we can make an informed decision, here. I also assume there will be a variant of the zip generators that doesn’t crash (the filtering version!) if the lists are not of equal length!?
