<P>The &#8220;Down with <TT>typename</TT>!&#8221; paper,
<A HREF="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0634r3.html">P0634R3</A>,
overlooked the case of a <I>conversion-type-id</I> in a
<I>conversion-function-id</I>:</P>

<PRE>
  template&lt;class T&gt; struct S {
    operator typename T::X(); //<SPAN CLASS="cmnt"> </SPAN>typename<SPAN CLASS="cmnt"> is not helpful here.</SPAN>
  };
</PRE>

<P>This context should be added to the list of contexts in which
a <I>qualified-id</I> is assumed to name a type.</P>
