UNSTABLE: New API, yet to be vetted.

A non-null pointer, represented as an object at runtime. The object's prototype is null and cannot be changed. The object cannot be assigned to either and is thus entirely read-only.

To interact with memory through a pointer use the UnsafePointerView class. To create a pointer from an address or the get the address of a pointer use the static methods of the UnsafePointer class.
