<P>[Moved to DR at October 2002 meeting.]</P>

<P>Does dropping a cv-qualifier on a reference binding prevent the binding
as far as overload resolution is concerned?
Paragraph 4 says "Other restrictions
on binding a reference to a particular argument do not affect the formation
of a conversion sequence."  This was intended to refer to things like access
checking, but some readers have taken that to mean that any aspects of
reference binding not mentioned in this section do not preclude the binding.</P>

<P><B>Proposed resolution (10/01):</B></P>

<P>In 12.2.4.2.5 [<A href="https://wg21.link/over.ics.ref#4">over.ics.ref</A>] paragraph 4 add the
indicated text:</P>
<BLOCKQUOTE>
Other restrictions on binding a reference to a particular argument <INS>that
are not based on the types of the reference and the argument</INS> do
not  affect  the formation of a standard conversion sequence, however.
