Yeah, I mentioned something like this in another post -- essentially 
using the keypath as a key in a flat dictionary.

Granted, this is not *the fastest* way by any means, just keeping 
balanace in mind.

I only meant that in the context of why I was willing to try IMP 
caching. Because I didn't have to change data structures, I could just 
try it out quickly.

I have no problem changing the internal representation in a way that 
leads to real speed increases while still keeping the complexity 
manageable.
