I like that one, but I'd stick the star to the generator (e.g. yield 
*sub_generator), the meaning being to "unpack" the generator into the 
yield, same as unpacking a sequence passed as function parameters.

As an extension, the syntax may even (though I'm not sure it'd be a good 
idea to do so) work with any iterable, behaving the same way (yielding 
the successive values of the iterable object)
