(If it explicitly raises StopIteration right there in the generator, it can be trivially converted into a return statement, anyway.) The return statement is an explicit indication that the generator should now return; permitting a StopIteration to bubble up through and out is the implicit option; but the 'plicitness' isn't necessarily obvious.
