Re: Operator overloading with returning lists?

in reply to Operator overloading with returning lists?

If your overloaded function was written in XS, I could imagine it might be possible to ignore the context and foricibly return multiple things. Just push everything onto the stack even though you're always in scalar context.

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.
