- (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 print (collect-void) (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.
