But conversely it forces the client code to handle the final value in
a way that is unlike all of the other values. So it is at least both
simpler and less simple.
What makes the final value so special anyhow? (I can’t think of any good
reasons, only bad ones – e.g. you have a narrow idea of the purpose of
generators, or you wish you could sometimes call a generator as a normal
function, etc.) Do they have any examples of where this helps?
