<P>[Accepted as a DR at the June, 2023 meeting.]</P>

<P>Subclause 7.6.2.8 [<A href="https://wg21.link/expr.new#1">expr.new</A>] paragraph 1 introduces the
grammar non-terminal <I>new-type-id</I>, but never specifies its
meaning.</P>

<P><B>Proposed resolution (approved by CWG 2023-06-12):</B></P>

<OL>
<LI>
<P>Change in 7.6.2.8 [<A href="https://wg21.link/expr.new#1">expr.new</A>] paragraph 1 as follows:</P>

<BLOCKQUOTE>

The <I>new-expression</I> attempts to create an object of
the <I>type-id</I> <DEL>(9.3.2 [<A href="https://wg21.link/dcl.name">dcl.name</A>])</DEL>
or <I>new-type-id</I> <INS>(9.3.2 [<A href="https://wg21.link/dcl.name">dcl.name</A>])</INS> to which it is
applied.  The type of that object is the allocated type. This type
shall be a complete object type (6.9.1 [<A href="https://wg21.link/basic.types.general">basic.types.general</A>]), but not
an abstract class type (11.7.4 [<A href="https://wg21.link/class.abstract">class.abstract</A>]) or array thereof
(6.8.2 [<A href="https://wg21.link/intro.object">intro.object</A>]).

<LI>
<P>Change in 9.3.2 [<A href="https://wg21.link/dcl.name#1">dcl.name</A>] paragraph 1 as follows:</P>

<BLOCKQUOTE>

To specify type conversions explicitly, and as an argument of sizeof,
alignof, new, or typeid, the name of a type shall be specified. This
can be done with a <I>type-id</I> <INS>or <I>new-type-id</I>
(7.6.2.8 [<A href="https://wg21.link/expr.new">expr.new</A>])</INS>, which is syntactically a
declaration for a variable or function of that type that omits the
name of the entity.
