It seems to me, the main benefit is for writers of nested generators and
co-routines. It makes those cases easier to debug, and may help generators
in general be more reusable, and reliable, in the context of nested
generators and co-routines.
Which if true could contribute to better, and more dependable,
multi-thread, multi-process, or even multi-core, software designs.
That is the general impression I get from the conversations about the
changes being made. But I'm not sure I can point to any one message
stating it like that.
Possibly someone can confirm if any of those points are valid and why.
Or it could be I'm just a bit too optimistic. ;-)
