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. ;-)
