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.
