No, just moving the issue to the iterator. Your iterator has exactly
the same structure in it.

Personally, I quite like assignment-in-conditional notation. Yes, it's
a pretty common cause of problems; but what happened to the
"consenting adults" policy? Python permits operator overloading and
even the reassignment of builtins, both of which can cause similar
confusion.

But, that's the choice Python's made. And being able to use the same
symbol for assignment and comparison does have its advantages.
