What is the status of any effort to implement a JIT or other compiler 
from bytecode to native execution?

Is it just too much work for someone or not really of interest because 
it is so easy to migrate code to primitives by compiling to C?  Being 
able to write the compiler in Smalltalk should help.

The Self team released their source, but it is a huge ball of 
uncommented C++ code.  Yuck.
