Of course, the fact that zip() is the shorter form that everyone is used to means that, even if a `strict` argument is added, few people will bother adding it. The possible solution is to introduce zip_shortest() with the current behavior of zip(), make zip() emitting a pending deprecation warning when some data is ignored, and after long period of deprecation make it raising an exception if some data is ignored. Wait, are suggesting that zip should raise by default (after a suitable deprecation period)? "if some data is ignored"
Even so, I don't think we could ever change the default to be to "raise unless all of the iterables are the same length". There's just too much code that would break. Eric
