Yeah, clumsy and suffering from code bloat - I'm already disturbed to
have one static block registering the bootstrap method for each class
(i.e. per compiled function). I'd have much preferred if bootstrap
method registration were inheritable. But that aside, after all
reflection will only be used the very first time the callsite is
linked, so it shouldn't be much of a problem.
