I don't feel comfortable with the idea exposed by Marc. Implementing
in C is not always possible. Sometime you want to implement Scheme on
a machine for which you don't have access to C (e.g. a JVM base
platform). An implementation should be reasonable even without C.
I don't think that (even for a prototype) we should rely on C.
