They claim that for even very large type hierarchies this only takes a 
small fraction of a second on a fast machine. And that they have an 
incremental version of their system (not described in the paper, I 
think) where this would be even less of a problem.

This would work very well with their system if you have one meta-object 
per "type partition", but I think it is the overhead of grouping 
objects into partitions that you are trying to eliminate, right?

The numbers in the paper were very interesting, though I think that 
there are far more "types" and messages in Self 4 than what they 
evaluated. I wonder if that would have any effect in the results.
