"return", like "break", causes the "else" suite to be skipped.
https://docs.python.org/3/reference/compound_stmts.html#the-for-statement
does not clearly specify this; it only says that the else suite is executed
when the iterator is exhausted or empty, and that "break" skips it. Perhaps
a sentence should be added to clearly and unambiguously state that "return"
skips it also?
