It would be nice to write a generator in such a way that, in addition

From Python 3.3, anything 'returned' becomes the value of the
StopIteration
exception, so it is possible, but not pretty.
Instead of -
my_gen = generator()
for item in my_gen():
do_something(item)
[how to get the final result?]
Currently, I don't believe there is a way.
I sometimes yield what would be a return value as the final item. Not very
happy with it though.
