Nice proposal! Unfortunately, there is no such thing as a "byte"
in Scheme. Hence, the portable way to get bytes (e.g. to be written
to a file as in the confidence tests) is (random (expt 2 32)) and then
decomposing the number into its bytes with modulo and quotient.
This is slow and clumsy.
I will think about it.
