Possibly. I wouldn't exactly call that "easy" though (unless you already
have a Y combinator handy). :) The recursive_memoizer class template is
designed to make that subtype of memoization problems trivial to implement.
In general, I'd say that memoization is not a conceptually difficult
idea, so the interfaces should reflect that.
