Well, specifically I'm curious about this approach for Reia.  Right now I've
had difficulty keeping the semantics consistent between the compiled and
evaluated versions (and this is using erl_eval to handle the evaluation).

I figure by using a compiled solution for eval there's a single path all
code goes through to get executed.

Unless you're crazy enough to pass more than 20 arguments :)

Oh right, crap... that's a tricky problem.  I can't think of a good solution
offhand either.
