Indeed - Greenlets allows you to build the functionality you propose without 
having to change the language.

This is easy enough to build using greenlets today. I tried writing an
experimental version of our generator scheduling system using greenlets
rather than generators and found it to work very nicely. I'd suggest that if 
you really want this functionality (I can understand why) that you revisit 
greenlets - they probably do what you want.
