This is similar to CACHE_MAP except that it handles result. Specifically, you can insert ('a, 'b) result Lwt.t and promises that are fulfilled with Error _ are treated like promises that are rejected:

They are removed from the cache automatically.
They are not folded over by fold.

Parameters

module C : Ringo.CACHE_MAP
