<pre>Should alignof(T[]) be legal if T is a complete object type (and therefore T[]
is an "array thereof") according to the first statement in [expr.alignof]?
5.3.6 Alignof [expr.alignof]
1 An alignof expression yields the alignment requirement of its operand type.
The operand shall be a type-id representing a complete object type or an array
thereof or a reference to a complete object type.
2 The result is an integral constant of type std::size_t.
3 When alignof is applied to a reference type, the result shall be the
alignment of the referenced type. When alignof is applied to an array type, the
result shall be the alignment of the element type.
I observed that g++ permits it.</pre>
