Not exactly what you're asking for, but Gambit is a Scheme implementation that compiles to C (or C++). You can define functions and specify what C ode should be used to implement them. So in a sense, mcros in Gambit end up generating C code. -- hendrik -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
