I complained about the use of "cache" in this name before, and I still
think that it is off-base. I'm not saying there isn't some definition
of the word that could cover what you're doing here, but it's not the
definition that is going to pop to mind for people reading the code.
I think "registry" would be OK; the fact that there is a registry does
not mean it is a global registry; it can be a registry of ephemeral
relations specific to that query. I'm sure there are other good
choices, too, but, please, not cache!
