Andre. The whole point of registers is that data entry is naturally terminated by either an "enter" or an operator. The data is loaded, and waits for the user to command it. This is unlike an algebraic (or operator prefix) system where the operator is entered between the operands, and therefore the process is locked into a prescribed state. You cannot change your mind, and add, instead of multiply, those two numbers you are interested in. The four register stack permits any number of levels of nested, complex chain calculations. This requires a separate temporary register in a prefix system.
But you know all that. I just think that a register based gadget would be easier to author than any other, and you could make it so those registers are visible, if you wanted to. Like that calculator I cannot remember...
