So would you mean something like:
<generator object <__main__.Foo instance at 0x835d0>, <__main__.Foo  
instance at 0x83620>, ...>
Or maybe:
<generator <__main__.Foo instance at 0x835d0>, <__main__.Foo instance  
at 0x83620>, ... >

While I agree in theory, I'm not sure I like the looks of it in  
practise.
