Comment:

 Accepting this on the basis of missing tests alone (I changed `memoize` to
 be a no-op and the full test suite runs without problems).

 As for the other issues described, maybe we could build `memoize` on top
 of `functools.lru_cache` [1].
 It's only available on python 3, but there is a backport available [2].
