Maybe it's so, but your explanation makes sense only in the context of
calling a machine-language function.  When we call Lisp or bytecode,
the machine-level operation is very different, and I cannot easily
correlate your description of using registers with what happens when
we call Lisp or bytecode.  Sorry for my misunderstanding.
