The nice thing would be that it would just a visitor… very similar to Opal: 1) do semantic analysis 2) a visitor emitting C code.

Later one could then even have a real intermediate representation (maybe the one of Sista?) and do some optimisation there, with all
control flow information instead of using the AST.

Ah, and there is Waterfall: http://hal.inria.fr/hal-00871353

This already contains a SLANG based on the RB AST… but compiling with native boost ASMJIT as a backend, not C.

Cool! I knew that Cami & Co. are working on something like that but not that they are so far.

We need to have both options, translate to C and to native code. One reason why I tried to make the translator standalone is to help to finally make VMMaker more modular. So the question is how far can we go to keep the linkage to VM development (that takes more Smalltalk implementations into account).
