I can't. :(
/* It's more efficient to use our own caching than the PMC's cache
Why? Because we also need to store state on what type of thing is
in the cache, and this can be one of three things. (four, if you
include "nothing") Four things is two bits, which means two flag
tests instead of one. Hence, we just use the old-style IOK/NOK/POK */

That's probably the right way to do it. But what about overlapping types
that are both integer and string OK?
