As far as I understand, "yield from" will always work, because a Future object can act like an iterator, and you can delegate your own generator to this iterator at the place of "yield from". "yield" only works if the parameter behind yield is already a Future object. Right Guido?
In case of sleep, sleep could be implemented to return a Future object. 2012/12/21 Laurens Van Houtven <_...@lvh.cc> > A generic comment on yield from APIs that I'm sure has been discussed in > some e-mail I missed: is there an obvious way to know up front whether > something needs to be yielded or yield frommed?
