It could be done, however, it directly affects performance of running code. The stack UNDO/REDO feature only takes a snapshot when the user starts a program from the UI, but never while a program is running so it doesn't cause any slowdown.
Making STO keep a copy of each thing it stores doubles (or more) the time it takes to store a variable, every single time you use STO, it can be disastrous for performance.

I wasn't thinking of having this feature active in programs; it is mistakes that I make from the keyboard that concern me! Thinking about it, it would be easy enough for a user to define a new STO command that places the old value in LAST_STO before storing the new value; can the user then bind this to the action of a left-shifted variable key?
