With the Mk functor, you can also directly provide a Cache module, which should have the signature Hashtbl.S. We will include your cache module and use it to define a memo function. It should be useful only if you want to use another Hashtbl implementation or things like this.

Parameters

module Cache : Hashtbl.S

Signature

include module type of struct include Cache end
