I'm beginning to think that it would be useful to add another ABC to collections.abc (and to typing) that represents the intersection of these three ABCs, and to "upgrade" Set and Sequence to inherit from it. (And Mapping.)
+1 on this, from the pytype side of things. pytype, during type-inference, always struggles to give names to things, and having additional structural types around helps. Also, I like "Collection" better than Reiterable, since the latter sounds too intricate, possibly scaring users away.
