Self seems to maintain a dependency graph and code
cache so that it can re-compile on the fly when it's assumptions
have been proven wrong.  So what it boils down to is
a tradeoff.  If you want to allow arbitrary manipulations to
first class environments, you either don't optimize the variable
lookup, or you keep around a dependency graph.
According to Chambers' thesis, the dependency graph can
get quite large (it seems to usually be about 2-3 times
larger than the code space!)
