		If applied to an expanded type, a copy will be manipulated.

feature -- Access

	object: ANY
			-- Associated object for Current.
			-- It might be a copy if Current is expanded.

	object_address: POINTER
			-- Unprotected reference to object.

	enclosing_object: separate ANY
			-- Enclosing object containing object or a reference to `object.

	physical_offset: INTEGER_32
			-- Actual offset in bytes of object in enclosing_object.

	copy_semantics_field (i: INTEGER_32): REFLECTED_COPY_SEMANTICS_OBJECT
			-- Object attached to the i-th field of object
			-- (directly or through a reference)

	expanded_field (i: INTEGER_32): REFLECTED_REFERENCE_OBJECT
			-- Object representation of the i-th field of object
			-- which is expanded. We provide a wrapper that enables
			-- direct editing of the field without duplicating
			-- the expanded object.
	
feature -- Settings

	set_object (a_obj: separate ANY)
			-- Update Current to represent a new reflected object.
