126.96.36.199.3 Requiring Non-Null Rest Parameters in the "Syntax" SectionIn some cases it is useful to refer to all arguments equally as a single aggregation using a rest parameter while at the same time requiring at least one argument. A variety of imperative and declarative means are available in code for expressing such a restriction, however they generally do not manifest themselves in a lambda list. For descriptive purposes within this specification,
F &rest arguments+
means the same as
F &rest arguments
but introduces the additional requirement that there be at least one argument.
