Correct, I didn't mean to talk about stream-pop/push, but first/rest.

Since first/rest do mean car/cdr in cl.el, having both sets makes sense. But I
also meant to comment on how we choose more streaming names in the future.

As someone else mentioned, lists and streams overlap at the notion of
sequences -- the main differences being the operational semantics of laziness,
and the semantics of allowing infinite streams.

So let's say I've written a function over lists, and I realize I want it to
act on streams instead. I'd hope that I could just insert "stream-" in several
places and fulfill that need. If I have to also change over to a different set
of names for the same effective operations, that would be unfortunate.

One could even imagine a wrapper library that works on both lists and streams
-- since lists are effectively pre-computed streams -- but that may be more
than we need just yet.
