[Voted into WP at April, 2006 meeting.]

Proposed resolution (October, 2005):

Add the indicated words to 6.7.2 [intro.object] paragraph 4:

If a complete object, a data member (11.4 [class.mem]), or an array element is of class type, its type is considered the most derived class, to distinguish it from the class type of any base class subobject; an object of a most derived class type, or of a non-class type, is called a most derived object.

The standard uses “most derived object” in some places (for example, Clause 3 [intro.defs] “dynamic type,” 7.6.2.9 [expr.delete]) to refer to objects of both class and non-class type. However, 6.7.2 [intro.object] only formally defines it for objects of class type.

Possible fix: Change the wording in 6.7.2 [intro.object] paragraph 4 from

an object of a most derived class type is called a most derived object

to

an object of a most derived class type, or of non-class type, is called a most derived object
