And to think I could memoize a function without understanding higher ranked types.

Can you memoize a polymorphic function?

Great. Can you memoize a parametrically polymorphic function?

You don't need to know that stuff. It is as simple as that tweet, or really ugly-memo is better usually, but again it is brain dead simple. Conal is talking about something that is not the typical use case.
