Please no.  We just decided to *not* extend the API.  The PEP originally
had a well designed list of dict API extensions that already provided
exactly that.  If we really want to provide access to that, we can roll
back to where we came from.

I don't think implementing an LRUCache on an ordered dict is a good
idea.  Especially because LRU caches are a shared resource and should be
thread safe because of that.  Which the ordered dict is not.
