There was a problem hiding this comment.
A small comment: With this definition we could not later write:
@_tp_cache(maxsize=200)
def __getitem__(self, parameters):
...This causes an error (function takes at least 1 argument...). I would propose to either make maxsize a constant MAXSIZE or use the decorator with args pattern here.
Except for this small comment, everything LGTM.

Fixes #290. Timing example:

That's about a 300x speedup!
