As I've already said, I'm strongly opposed to your patch series.
Rigging the core procedure call mechanisms to automatically convert
between a single value of SCM_UNDEFINED and zero values is terrible, for
multiple reasons.  It muddies the semantics and adds overhead to a
mechanism that needs to be as simple and lightweight as we can possibly
make it, especially when we move to native code generation.
