The closest to that I know of is this one:
Or you can apply this monad transformer to a probability monad:

Mostly we preferred (as do the domain experts we target) to write
probabilistic models in direct style rather than monadic style.
Haskell's laziness doesn't help -- in fact, to avoid running out of
memory, we'd have to defeat that memoization by sprinkling "() ->"
throughout the types.
