A library for generating random numbers in a memoized manner. Implemented as a
lazy table indexed by serialized StdGen. Monomorphism is used to
facilitate memoization, users should adapt their design to work with random
Int values only.
In a benchmark, the initial generation of 100000 random Ints took 10.30
seconds and consumed 2.5 gigabytes of memory. Generating the 100000 Ints
again from the same seed only took 2.06 seconds, a 5-fold speedup thanks to
memoization!
Incidentally, generating the 100000 Ints with the non-memoized function took
0.12 seconds, but that of course lacks all the benefits of memoization.
