One reason against this is simply that all the other constructs
(block/stream cipher, hashes) are classes, it would be odd for there
to be a single exception. A better reason is the data structure has
no way to implement generateKeyPair.

Because MonadRandom dictates mtl, and is heavier weight than a single
class. I was hoping to keep this agnostic (mtl is only required for
testing or benchmarks in crypto-api). If MR the more agreeable path
then I'll do it, though this means I use the unholy "fail" function.
Even if that's the case (and more people weighing in would help) I
still want to include Data.Crypto.Random and welcome comments.
Cheers,
Thomas
