Common Super Type for Boxed Types and Array Types

[Suminda Sirinath Salpitikorala Dharmasena]

Hello,

Some of the boxed types device directly from Object. Also, the array types
derive from Object.

This is sometimes inconvenient when pacifying API signatures and bounds.

So is it possible to consider a hierarchy like:
- BoxedPrimitive
  - Number
    - Integer
    - ...
  - Boolean
  - Character
- Array
  - PrimitiveArray
    - NumberArray
      - int[]
      - ...
  - boolean[]
  - character[]
  - ObjectArray<T>
