<P>[Voted into WP at April 2003 meeting.]</P>

<P>A use of an injected-class-name in an elaborated-type-specifier
should not name the constructor of the class, but rather the class itself,
because in that context we know that we're looking for a type.
See <A HREF="147.html">issue 147</A>.</P>

<P><B>Proposed Resolution (revised October 2002):</B></P>

<P> This clarifies the changes made in the TC for issue 147.</P>

<P>In 6.5.5.2 [<A href="https://wg21.link/class.qual#1">class.qual</A>] paragraph 1a replace:</P>
<BLOCKQUOTE>
If the <I>nested-name-specifier</I> nominates a class C, and the name
specified after the <I>nested-name-specifier</I>, when looked up in C, is the
injected class name of C (Clause 11 [<A href="https://wg21.link/class">class</A>]), the name is instead
considered to name the constructor of class C.
</BLOCKQUOTE>
<P> with </P>
<BLOCKQUOTE>
In a lookup in which the constructor is an acceptable lookup result,
if the <I>nested-name-specifier</I> nominates a class C and the name
specified after the <I>nested-name-specifier</I>, when looked up in C, is the
injected class name of C (Clause 11 [<A href="https://wg21.link/class">class</A>]), the name is
instead considered to name the constructor of class C.
[Note: For example, the constructor is not an acceptable lookup result in an
elaborated type specifier so the constructor would not be used in place
of the injected class name.]
</BLOCKQUOTE>

<P>Note that <A HREF="263.html">issue 263</A> updates a part of the
same paragraph.</P>

<P>Append to the example:</P>
<PRE>
  struct A::A a2;  // object of type A
</PRE>
