So what we have now is:

  (1) plain iterators

  (2) generator iterators

  (3) coroutine generator iterators

At the moment (2) and (3) are unified, which you don't like. (1) and (2)
are not unified, which I don't like.

You and I can pretend (2) didn't have send(), throw() and close() and be
satisfied. Then, generator iterators are just plain iterators from the
point of view of the application programmer.

However, it seems to me close() is intended to be used for (2) as well.
The way I'm reading PEP 342, it seems to encompass the objectives of the
rejected PEP 325  ("Resource-Release Support for Generators"):
