Suggestion: ParamKeyedCache.

I don't like Parameterized because it makes it sound like the cache is
parameterized (e.g. size), rather than using Param values as the keys
for the cache.  ParamKeyed indicates that Params are the key, rather
than configuring the cache...

I don't like "result cache" all that much, because it does sound like
we'd be caching query results etc, or that it might be referring to
Result nodes. Neither of which is the case...
