Could we add the following methods to the Class class?

T[] emptyArray() T[] newArray(int size)

I prototyped these, and they work fine for reference types but fall apart for primitive arrays. There is a Class literal for int.class, but we can't make it return an int[] with this method. (This is one reason that Array.newInstance returns Object.) Performance testing would be needed to ensure they are competitive with alternatives.
