;;; Commentary:
;; Implementation of SRFI-16. `case-lambda' is a syntactic form
;; which permits writing functions acting different according to the
;; number of arguments passed.
;;
;; The syntax of the `case-lambda' form is defined in the following
;; EBNF grammar.
;;
;; <case-lambda>
;; --> (case-lambda <case-lambda-clause>)
;; <case-lambda-clause>
;; --> (<signature> <definition-or-command>*)
;; <signature>
;; --> (<identifier>*)
;; | (<identifier>* . <identifier>)
;; | <identifier>
;;
;; The value returned by a `case-lambda' form is a procedure which
;; matches the number of actual arguments against the signatures in
;; the various clauses, in order. The first matching clause is
;; selected, the corresponding values from the actual parameter list
;; are bound to the variable names in the clauses and the body of the
;; clause is evaluated.
;;; Code:
(define-module (srfi srfi-16)
#:re-export (case-lambda))
;; Case-lambda is now provided by core psyntax.
