<P>[Voted into the WP at the February, 2012 meeting;
moved to DR at the October, 2012 meeting.]</P>



<P>There is a contradiction between the grammar of 9.3 [<A href="https://wg21.link/dcl.decl#4">dcl.decl</A>] paragraph 4
and that of 9.3.4.6 [<A href="https://wg21.link/dcl.fct">dcl.fct</A>] paragraphs 1 and 2 and
9.6.1 [<A href="https://wg21.link/dcl.fct.def.general#2">dcl.fct.def.general</A>] paragraph 2 regarding the placement of the
optional <I>exception-specification</I>: in the former, it immediately
follows the <I>parameter-declaration-clause</I>, while in the latter it
follows the <I>exception-specification</I>.</P>

<P><B>Proposed resolution (August, 2011):</B></P>
