Your objection is well-taken. The use of the zero-argument
case does not always work; it is merely intended for convenience,
to allow omission of :INITIAL-VALUE in the common cases.
It allows some situations to work which otherwise would be
errors. If the function can't accept zero arguments, all that
differs is that you get an error about wrong number of
arguments rather than about an empty sequence to REDUCE.
