This in itself isn't really an argument, is it?

It seems that people have been coming up with several creative uses
for generators, such as David Mertz's weightless threads, where the
main point of the yield is to freeze the execution of the generator,
not to return an object. This may break the intent behind the iterator
protocol, but it is the only way of achieving this sort of
functionality...

So, basically the question was "why is it thus?" and your answer is
that you think it should be...? Fair enough :)
