=={{header|Wart}}==
Wart defines queues as lists with a pointer to the last element saved for constant-time enqueuing:
<lang python>def (queue seq)
(tag queue (list seq lastcons.seq len.seq))
Line 4,179:
<code>empty?</code> relies on <code>len</code> by default, so there's no need to separately override it.
