1.4.4.20.2 Naming Conventions for Rest Parameters

Within this specification, if the name of a rest parameter is chosen to be a plural noun, use of that name in parameter font refers to the list to which the rest parameter is bound. Use of the singular form of that name in parameter font refers to an element of that list.

For example, given a syntax description such as:

F &rest arguments

it is appropriate to refer either to the rest parameter named arguments by name, or to one of its elements by speaking of ``an argument,'' ``some argument,'' ``each argument'' etc.
