That’s true, but as the Forth is top of stack I’d read it as the subject and I as the object. OFC that’s just how you define the heart-word, but still.
The operand at the top of the stack is used as the second operand for binary operators. Second from the top is used as the first operand.
Here illustrated using dc, and doing the calculation 3 - 1 and printing the answer with the command p, getting the result of 2. As we can see here with a noncommutative operation (subtraction), in order to illustrate the point, we get 2, rather than -2.
But just to nitpick, wouldn’t this parse into “Forth ❤️ I”? Which is to say, aren’t the operands in the wrong order?

Neither Forth nor I are actions.
