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 without 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
Like force except that if the computation of x raises an exception, it is
unspecified whether force_val x raises the same exception or Undefined.
val from_fun : (unit -> 'a) -> 'a t
from_fun f is the same as lazy (f ()) but slightly more efficient.
val from_val : 'a -> 'a t
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 is_val : 'a t -> bool
is_val x returns true if x has already been forced and
did not raise an exception.
