Performance - anyway to limit calls to matchesMethod()

[mmucklo]

In doing example 2, I noticed that my matchesMethod() function seems to be called for a host of different functions before it finds one that matches.

I'm concerned about the performance effects of this - so my question is whether there's a way to improve production performance by only calling matchesMethod on the functions that it needs to via some kind of pre-caching steps (and or the same for matchesClass)?
