I have to say, this starts to sound more and more like homework. That, or you're just plain lazy and expect us to do your work.

Lazy(3o) OCaml library Lazy(3o)
NAME
Lazy - Deferred computations.
Module
Module Lazy
Documentation
Module Lazy
: sig end
Deferred computations.
type 'a t = 'a lazy_t
A value of type 'a Lazy.t is a deferred computation, called a suspension, that has a result of type 'a . The special expression syntax
lazy (expr) makes a suspension of the computation of expr , without computing expr itself yet. "Forcing" the suspension will then compute
expr and return its result.
Note: lazy_t is the built-in type constructor used by the compiler for the lazy keyword. You should not use it directly. Always use
Lazy.t instead.
Note: Lazy.force is not thread-safe. If you use this module in a multi-threaded program, you will need to add some locks.
Note: if the program is compiled with the -rectypes option, ill-founded recursive definitions of the form let rec x = lazy x or let rec x =
lazy(lazy(...(lazy x))) are accepted by the type-checker and lead, when forced, to ill-formed values that trigger infinite loops in the
garbage collector and other parts of the run-time system. Without the -rectypes option, such ill-founded recursive definitions are
rejected by the type-checker.
exception Undefined
val force : 'a t -> 'a
=== force x forces the suspension x and returns its result. If x has already been forced, Lazy.force x returns the same value again with-
out recomputing it. If it raised an exception, the same exception is raised again. Raise Undefined if the forcing of x tries to force x
itself recursively. ===
val force_val : 'a t -> 'a
force_val x forces the suspension x and returns its result. If x has already been forced, force_val x returns the same value again without
recomputing it. Raise Undefined if the forcing of x tries to force x itself recursively. If the computation of x raises an exception, it
is unspecified whether force_val x raises the same exception or Undefined .
val lazy_from_fun : (unit -> 'a) -> 'a t
lazy_from_fun f is the same as lazy (f ()) but slightly more efficient.
val lazy_from_val : 'a -> 'a t
lazy_from_val v returns an already-forced suspension of v This is for special purposes only and should not be confused with lazy (v) .
val lazy_is_val : 'a t -> bool
lazy_is_val x returns true if x has already been forced and did not raise an exception.
