<P>[Voted into the WP at the March, 2011 meeting as part of paper N3262.]</P>



<P>The changes for <A HREF="990.html">issue 990</A> did not address
the description of overload resolution when an argument is an empty
<I>braced-init-list</I>.  For example:</P>

<PRE>
    struct A {
      A();
      A(std::initializer_list&lt;int&gt;);
      A(std::initializer_list&lt;double&gt;);
    };

    A a{};       //<SPAN CLASS="cmnt"> OK</SPAN>

    void f(A);

    void g() {
      f({});     //<SPAN CLASS="cmnt"> ambiguous</SPAN>
    }
</PRE>
