allocatorObject

Returns a dynamically-typed CAllocator built around a given statically- typed allocator a of type A. Passing a pointer to the allocator creates a dynamic allocator around the allocator pointed to by the pointer, without attempting to copy or move it. Passing the allocator by value or reference behaves as follows.

• If A has no state, the resulting object is allocated in static

  shared storage.

• If A has state, the result will move

  the supplied allocator A a within. The result itself is allocated in its own statically-typed allocator.
