there's significant overhead, but could easily be reduced to one
global table, one table per object instance, and one closure per
instance method that's actually used.
roughly what the original poster had in mind, and not too different
from the closure-based OOP mentioned by David Given. it's, in fact, a
lazy implementation of the same. very similar to how Python works.
