description:

  A simple probability distribution type, where distributions are characterized
  by sampling functions.
  .
  This implementation is a thin layer over @mwc-random@, which handles RNG
  state-passing automatically by using a @PrimMonad@ like @IO@ or @ST s@ under
  the hood.
  .
  /Examples/
  .
  Transform a distribution's support while leaving its density structure
  invariant:
  .
  > -- uniform over [0, 1] to uniform over [1, 2]
  > succ <$> uniform
  .
  Sequence distributions together using bind:
  .
  > -- a beta-binomial conjugate distribution
  > beta 1 10 >>= binomial 10
  .
  Use do-notation to build complex joint distributions from composable,
  local conditionals:
  .
  > hierarchicalModel = do
  >   [c, d, e, f] <- replicateM 4 $ uniformR (1, 10)
  >   a <- gamma c d
  >   b <- gamma e f
  >   p <- beta a b
  >   n <- uniformR (5, 10)
  >   binomial n p
