Using the implementation from [[Queue/Definition#Phix|Queue/Definition]]

<lang Phix>~~?empty~~() -- 1

with javascript_semantics

push(5)

printf(1,"empty:%t\n",empty()) -- true

?empty() -- 0

push_item(5)

push(6)

printf(1,"empty:%t\n",empty()) -- false

?pop() -- 5

push_item(6)

?pop() -- 6

printf(1,"pop_item:%v\n",pop_item()) -- 5

?empty() -- 1</lang>

printf(1,"pop_item:%v\n",pop_item()) -- 6

printf(1,"empty:%t\n",empty()) -- true

Using the builtins (same output):

with javascript_semantics

constant queue = new_queue()

printf(1,"empty:%t\n",queue_empty(queue))

push(queue,5)

printf(1,"empty:%t\n",queue_empty(queue))

push(queue,6)

printf(1,"pop:%v\n",pop(queue))

printf(1,"empty:%t\n",queue_empty(queue))
