This library provides a type class `Memoizable` for memoizing
functions, along with instances for a variety of argument types.
It includes a Template Haskell function for deriving
`Memoizable` instances for arbitrary algebraic datatypes.

The library constructs pure memo caches without the use of
`unsafePerformIO`.  This technique relies on implementation
assumptions—namely, *call-by-need*—that, while not guaranteed
by the semantics of Haskell, generally appear to hold.
