[Python-ideas] A send() built-in function to drive coroutines

[Luciano Ramalho]

My previous pseudo-code lost the result of next(coroutine) -- which
may or may not be relevant.

I amended the send() code and wrote a few examples of it's use in a gist:

Now the user can decide whether or not to ignore the result of the
priming next() call.

Best,

Luciano
