I'm not sure I understand your question. The same use case as for
`itertools,chain`: When you have several generators you want to iterate
over, one after another. (True, it might be not as good when you have more
than 2.)

I could use `itertools.chain`, but why type so much? I think if you have two
generators, g1 and g2, then it makes sense that g1 + g2 will be an iterator
that goes over the elements of both of them.

About `generator.send`, I don't understand how it's related. But I'm still
new to this.
