A small progress update on this:

* There now is support for yield by reference
* Generators are now automatically detected by the presence of "yield"
instead of requiring the "*" modifier.

The main open point I still have is whether or not generators should
have a throw() method (=E1 la Python). I couldn't yet find a convincing
use case for it, so I'm considering to just leave it out.

If there is any further feedback on the proposal, I'd love to hear it :)
