Yes, and it you'd also introduce items with different types onto the
evaluation stack.  This makes for a significantly more complex
definition.  What does it mean if the expression indicates to add a
float value to an address?  Probably an error, but ???  Also is an
efficiency issue to have a stack with with objects of variable sizes.
