<P>[Moved to DR at the April, 2013 meeting.]</P>

<P>One of the bullets in 9.5.5 [<A href="https://wg21.link/dcl.init.list#3">dcl.init.list</A>] paragraph 3 reads,</P>

<BLOCKQUOTE>

Otherwise, if T is a reference type, a prvalue temporary of the type
referenced by T is list-initialized, and the reference is bound to
that temporary.

</BLOCKQUOTE>

<P>This does not say whether the initialization of the temporary is
direct-list-initialization, copy-list-initialization, or the same
kind of list-initialization as the top-level initialization.</P>

<P><B>Proposed resolution (December, 2012):</B></P>

<P>Change 9.5.5 [<A href="https://wg21.link/dcl.init.list#3">dcl.init.list</A>] paragraph 3 as follows:</P>

<UL>
<LI><P>...</P></LI>

<LI><P>Otherwise, if <TT>T</TT> is a reference type, a prvalue
temporary of the type referenced by <TT>T</TT> is
<DEL>list-initialized</DEL> <INS>copy-list-initialized or
direct-list-initialized, depending on the kind of initialization for
the reference</INS>, and the reference is bound to that
temporary. [<I>Note:</I> As usual...</P></LI>

<LI><P>...</P></LI>
