If func is expensive, you could try memoizing it. Then subsequent
calls just do arg lookups. Michele Simianato has posted a good
memoizing decorator on the Python wiki.

That's the trick! I almost forgot about that one.

I am pretty sure that the sorted() construct cannot be improved much
further, but...

Don't use a generator then. If you're going to finally return a list (and
sorted does exactly that), build a list right from the start:
Good point. However, for the sake of argument, what if I removed the
sorting requirement and simply wanted the generator? I usually strive
for comprehensions
