<P>[Moved to DR at 10/01 meeting.]</P>

11.4.7 [<A href="https://wg21.link/class.dtor#12">class.dtor</A>] paragraph 12 contains the following note:

<BLOCKQUOTE>

an explicit destructor call must always be written using a member
access operator (7.6.1.5 [<A href="https://wg21.link/expr.ref">expr.ref</A>]); in particular, the
<I>unary-expression</I> <TT>~X()</TT> in a member function is not an
explicit destructor call (7.6.2.2 [<A href="https://wg21.link/expr.unary.op">expr.unary.op</A>]).

</BLOCKQUOTE>

<P>This note is incorrect, as an explicit destructor call can be
written as a <I>qualified-id</I>, e.g., <TT>X::~X()</TT>, which
does not use a member access operator.</P>

<P><B>Proposed resolution (04/01):</B></P>

<P>Change 11.4.7 [<A href="https://wg21.link/class.dtor#12">class.dtor</A>] paragraph 12 as follows:</P>

<BLOCKQUOTE>

[<I>Note:</I> an explicit destructor call must always be written
using a member access operator (7.6.1.5 [<A href="https://wg21.link/expr.ref">expr.ref</A>])
<INS>or a <I>qualified-id</I> (_N4567_.5.1.1 [<A href="https://wg21.link/expr.prim.general">expr.prim.general</A>])</INS>;
in particular, the <I>unary-expression</I> <TT>~X()</TT> in a
member function is not an explicit destructor call
(7.6.2.2 [<A href="https://wg21.link/expr.unary.op">expr.unary.op</A>]).]
