I had a go at a generic memoize to wrap functions, including
possibly anonymous functions.  It started as a way to write a
few recurrences in a simple-minded way, then got a bit carried
away.  The cutest bit is that because it can be applied to an
existing function you can experiment with memory vs time for
possibly re-used values.
