<P>[Voted into WP at March, 2010 meeting.]</P>

<P>It is not clear from the specification in 9.9.2 [<A href="https://wg21.link/namespace.def#8">namespace.def</A>] paragraph 8
how a declaration in an inline namespace should be handled if
the name is the same as one in the containing namespace or in an parallel
inline namespace.  For example:</P>

<PRE>
  namespace Q {
    inline namespace V1 {
      int i;
      int j;
    }
    inline namespace V2 {
      int j;
    }
    int i;
  }
  int Q::i = 1;   // Q::i or Q::V1::i?
  int Q::j = 2;   // Q::V1::j or Q::V2::j?
</PRE>

<P><B>Proposed resolution (July, 2009):</B></P>

<P>This issue is resolved by the resolution of <A HREF="861.html">issue 861</A>.</P>
