ok, I see. Have you considered extending the class PackageInfo with these caches instead?

Probably what would be tricky, is when to reset these caches. These could be done using the system change notification I imagine.

The big problem is then that I can't assume that I know all class extensions within the class, because other packages (which I don't necessarily import) may do some. To do that, I should ask all methods within each imported class for its most specific package. This was more or less the situation we had before the cache, which brought the system to its knees on large projects. Perhaps I will try tomorrow but I don't have high hope.
