include Module_types.MONAD with type 'a t = 'a option
val return : 'a -> 'a t
return a
makes a monadic container containing the value a
.
m >>= f
extracts the value a
from the monadic container m
and returns f a
.
f >=> g
composition of the two monadic functions f
and g
.
f >=> g
is equivalent to fun a -> f a >>= g
.
map f m
maps the values in the monadic container m
with the function f
.
