Although it makes sense to have the same code dealing with all that 
kind of caching, it doesn't make sense (to me) to have a unified cache 
for these things - I hope you didn't mean that.
Using a hash to do some sort of a "fuzzy" search wouldn't be too good. 
If this is really required often and arbitrary, we could connect 
different 8 (or whatever) bit hash tables together. But I am not sure 
if this is the right "container" for such a thing.

Adios...
