Re^2: Operator overloading with returning lists?

[JavaFan]

I don't think that will work if the caller expects just one return value.

I'm just saying it's theoretically possible to violate your caller this way even if it wasn't expecting it.

The problem is that if your XS pushes multiple things on the stack, and the caller expects just one, the caller will pop up just one thing of the stack, leaving the rest there.
