Re: Multiple output arguments
If two values are sufficiently closely related to warrant being returned at the same time from a function, then those two values deserve to be encapsulated into a single object. From the example, I would assume that x and y are coordinates of a 2d point. You should be passing around Point2D objects in that case, not separate values.
Correct is better than fast. Simple is better than complex. Clear is better than cute. Safe is better than insecure.
