Oh right, sorry, you don't want to pay for boxing the double. Yeah this is the case where you'd want to go with a tuple. If this really was common in my own code I would probably write a mutable tuple macro. But I totally understand why someone else might just write the Java if they just want performance and just don't want to bother.
