module Monad: sig .. end
t >>= f returns a computation that sequences the computations
represented by two monad elements. The resulting computation first does
t to yield a value v, and then runs the computation returned by f v.
module type Basic = sig .. end

module type S = sig .. end
module Make:
module type Basic2 = sig .. end
Multi parameter monad.
module type Infix2 = sig .. end
Same as Infix, except the monad type has two arguments.
module type S2 = sig .. end
The same as S1 except the monad type has two arguments.
