Of course.  Are you ok when `stream-pop' would raise a (newly defined)
error when called on an empty stream?

The problem is how one can notice when a stream has run out of elements
when calling `stream-pop'.  We could either just return nil (bad,
because the stream could also generate nil if non-empty), return a
dedicated flag (like an uninterned symbol that is internal to
stream.el), or just signal a dedicated error that the programmer has to
catch.  I vote for the third alternative.
