Sounds interesting.  I use an intermediate representation also in the BC
compiler before generating bytecodes.  It helps me find shared vars
between contexts/closures.  I also use it for a couple of simple
optimizations.  Maybe we can share some code ideas.  Maybe we can add
block closures to your compiler or we can add native code generation to
mine (or some combination there of).  You can find my code on the swiki
at http://minnow.cc.gatech.edu/squeak/BlockClosureVersion.

PS. By the way, the block closure page is the first one listed under
Google when searching for "block closures".  Cool!
