That looks fine to me, except of course it doesn't work :(
Instead you get set([2, 3, 5, 7]), which is much less attractive and
introduces an unneeded intermediate data structure. Or set((2, 3, 5,
7))... which is typographically prettier, but probably more confusing to
a newbie.
Generator comprehensions + dict() were a nice alternative to dict
comprehension, and also replace the need for set comprehension. I feel
like there might be some clever way to constructing sets? Not that
there's any direct relation to generator expressions that I can see, but
maybe something in the same vein.
