- list-queue-append! list-queue ...procedure
Returns a list queue which contains all the elements in front-to-back order from all the list-queues in front-to-back order. It is an error to assume anything about the contents of the list-queues after the procedure returns. This operation is O(n) in the total number of queues, not elements. It is not part of the R7RS-small list API, but is included here for efficiency when pure functional append is not required.
