Re: [Python-Dev] Obtaining stack-frames from co-routine objects

I wonder if in 3.6 it might be possible to *add* some bookkeeping to "await" and "yield from" expressions that provides external visibility into the underlying iterable or coroutine that the generator-iterator or coroutine has delegated flow control to.

In my original implementation of yield-from, stack frames had an f_yieldfrom slot referring to the object being yielded from. I gather that slot no longer exists at the C level, but it ought to be possible to provide a Python attribute or method returning the same information. -- Greg
