I think you're making the same mistake as Bob. Assignments aren't equations.

x := x + 1 definitely not an equation.

It may be desirable to have a programming language that can solve systems of equations, but....

x + y := 3 definitely not an equation. x - y := 1 definitely not an equation.

The result?

x = 2 and y = 1? possible. x = 503423 and y = 503422? also possible. x = -324 and y = -325 also possible.

I think it defies logic for assignment to be anything but deterministic.
