I did.  I'm not sure it's necessary though.  This isn't in the fast
path, so the performance benefit doesn't really help.  I think it's
less complex to put all of this logic into a single function, instead
of having to main a data structure as a cache.  Mostly a personal
preference though, I'd be happy to change it.

I've addressed the rest of your comments in the version I'll be
sending out soon.

Thanks,
Ethan
