I'm genuinely torn.  The elegance of the solution far
outweighs its esotericness.  And I certainly can't
complain about the choice of the problem (finding
primes), since I included a much more pedestrian
solution to the same problem on the very page that
we're talking about.

I do feel, however, like I want to order solutions by
how long they are in line numbers, and if I stick to
that rule, I do think that the solution above, while
elegant, might be a little advanced as the seventh
example of Python's simplicity.

Is there a way to broaden the problem somehow, so that
it can be a longer solution and further down on the
page, and so that I can continue to enforce my
somewhat arbitrary rule of ordering examples by how
long they are?

(I fully confess that my ordering rule unfairly
penalizes short-and-sweet limitations, but I hope that
*all* solutions are short-and-sweet, and this one
certainly fits the bill.)
