    Efficiency?  Lisp is not a statically typed language.  We don't know
    the type of the arguments until after they have been evaluated.

All the args have been evaluated by the time the function is called.
It just has to check their types and maybe convert the first arg
to floating point.

    Also (/ 5 4 2.3) would no longer be equivalent to (/ (/ 5 4) 2.3).

I don't think that is a big loss.
