Consider, for programmatic management of request.args how this simple
modification of deque language
might help suggest useful things to do with this new class:

left-end of list / bottom-of-stack / front-of-que:

pull();    pull from the start of the list; pull from the bottom of the
stack...  same as deque's popleft()
push();  push onto the head of the list; push onto the bottom of the
stack.... same as deque's appendleft()

right-end of list / top-of-stack / last-in-end of que:

put();   put on the top of the stack, end of que.... same as deque's and
list's  append() (which is equivalently good lanugage)
pop();  as current...
