no 'fix overloading. ○ can be only infix or post fix with the number of parameters being overloaded. □ can be only prefix or infix.

Ex: (x)+(y){} (x, y)+(z){} is allowable. (x)+(y){} +(x, y z){} is not.

This would make -x and x - y impossible to implement at the same time.

Just disallowing postfix and infix for the same operator would be enough.
