(collect-void #!optional (sentinel (void)))procedure

A collector that does nothing and returns an unspecified value (as if calling (void)). This is useful if your transducer is meant to only incur side effects:

(import transducers)

(transduce list-fold
           (list "Each" "String" "Prints" "on" "its" "own" "line"))

; Each
; String
; Prints
; on
; its
; own
; line

A short hand for doing this is provided by the for-each procedure in this module.
