This is the problem with python's conflation of iterable and iterator, and maybe why so many programmers don't understand the difference when they pick up Java.

It really is not. It’s just a natural outcome of imperative langages. If operations can have side-effects, then combinator behaviour will affect those side-effects.
You could do the same with iterables with side-effecting iterations.
It’s also perfectly logical to be able to iterate an iterator.
