[Python-Dev] PEP 492: What is the real goal?

[Guido van Rossum]

Maybe it would help to refer to PEP 342, which first formally introduced
the concept of coroutines (as a specific use case of generators) in Python.
Personally I don't care too much which term the PEP uses, as logn as it
defines its terms. The motivation is already clear to me; it's the details
that I care about before approving this PEP.
