      There are some functions and predicates which we tend to think of as being able to take any number of parameters – of being of variable arity or variadic.
    • 2004, François Récanati, Literal Meaning[2], Cambridge University Press, →ISBN, page 109:

    • 2006, Nils M. Holm, Sketchy LISP: An Introduction to Functional Programming in Scheme[3], Second Edition edition,, →ISBN, page 53:
      However, the real max procedure of Scheme is a variadic procedure, which means that it accepts any positive number of arguments: ¶ (max 5 1 3 8 9 7 2 6 4) => 9
