Your example only proves your point if every instance of x is the same x, with the same objective value. i.e., what if x/x is actually (x=5.0)/(x=3.0) ?

x can't be two values at the same time. It's one instance, not a class.

If you have "scope1.x/scope2.x" then they don't cancel out, but that's not "x/x"

And if you save a value for later, and change x, then that value isn't x anymore.

(I assume you're using = to state the value, not as an assignment operator.)

Then you're computing x/y and not x/x...
