-  The GUI isn't terribly smart.  It doesn't handle exceptions very well, such as
-  trying to pop from an empty stack, or trying to perform a calculation on an
-  insufficient number of arguments.  It also won't be very happy to receive
-  ill-formed numbers; basically, there's very little error checking.
