<P>[Accepted at the November, 2020 meeting as part of paper P1787R6 and
moved to DR at the February, 2021 meeting.]</P>



<P>
<A HREF="1477.html">Issue 1477</A> assumes that a name
declared only in a <TT>friend</TT> declaration can be defined outside
its namespace using a <I>qualified-id</I>, but the normative
passages in 9.3.4 [<A href="https://wg21.link/dcl.meaning#1">dcl.meaning</A>] paragraph 1 and
_N4868_.9.8.2.3 [<A href="https://wg21.link/namespace.memdef#2">namespace.memdef</A>] paragraph 2 do not settle the question
definitively, and there is implementation variance.  A clearer
statement of intent is needed.</P>
