Comment (by bouke):
As discussed on IRC, a few benchmarks comparing `memoize` with `lru_cache`
and `lru_cache`'s backport. Also, another column with the statistics
bookkeeping in the backport disabled for extra speed. These results are
achieved with `maxsize=None`.
{{{
+-------+---------+-----------------+----------+----------+
| | memoize | lru_cache (py3) | backport | no-stats |
+-------+---------+-----------------+----------+----------+
| write | 0.970 | 2.373 | 2.714 | 2.413 |
| read | 0.342 | 0.830 | 1.053 | 0.950 |
+-------+---------+-----------------+----------+----------+
