The compiler that Hannes is referring to has evolved into the Closure
Compiler which uses the Refactory parse nodes, and no longer requires VM
or image format changes.  Load SmaCC Development from SqueakMap to get
the Refactory parse nodes and the parser generator (the parse node
classes can be found in system category 'Refactory-Parser' once loaded).
 Load ClosureCompiler-ajh from SqueakMap to get the closure compiler
which includes an intermediate representation (IRBuilder) and a bytecode
assembler (BytecodeGenerator).  Read the class comment in Compiler to
start (after ClosureCompiler is loaded).

Yes, I think we should include the Closure Compiler in the next release
(3.7).
