<P>[Accepted as a DR at the November, 2022 meeting.]</P>

<P>Clause Annex B [<A href="https://wg21.link/implimits#2.3">implimits</A>] bullet 2.3 specifies:</P>

<BLOCKQUOTE>

<UL>
<LI>
Pointer (9.3.4.2 [<A href="https://wg21.link/dcl.ptr">dcl.ptr</A>]), array
(9.3.4.5 [<A href="https://wg21.link/dcl.array">dcl.array</A>]), and function
(9.3.4.6 [<A href="https://wg21.link/dcl.fct">dcl.fct</A>]) declarators (in any combination)
modifying a class, arithmetic, or incomplete type in a declaration
[256].
</LI>
</UL>

</BLOCKQUOTE>

<P>This omits function types as the to-be-modified type, and ignores
pointer-to-member declarators.</P>
