Yes, it seems useful. But should it be:
val wrap : ('a -> 'b) -> 'a -> 'b t
or:
val wrap : (unit -> 'a) -> 'a t
?
I would tend for the second solution because if you are wrapping a
function that takes multiple arguments you are going to write:
wrap (fun () -> f x y z) ()
anyway. Plus maybe wrap1, wrap2, ..., wrapn for a reasonable value of n.
