I like the stack-based options. It reminds me of Reverse Polish Notation on
my HP 48G (which was sadly lost). I don't think the problem is with the
stack notation itself, but just with how the change affected the semantics
of the apply-change task (and maybe other tasks that take streams of
different types). That was what I was referring to when I suggested it may
be too disruptive to change (by change I meant reverse the order of the
arguments to the apply-change task, not change back to a queue system).
