<BLOCKQUOTE>

<P><B>Proposed resolution (February, 2012):</B></P>

<P>Change 7.6.1.8 [<A href="https://wg21.link/expr.typeid#5">expr.typeid</A>] paragraph 5 as follows:</P>

<BLOCKQUOTE>

<DEL>The top-level cv-qualifiers of the glvalue expression or the
<I>type-id</I> that is the operand of <TT>typeid</TT> are always
ignored.</DEL> <INS>If the type of the expression or <I>type-id</I> is
a cv-qualified type, the result of the <TT>typeid</TT> expression
refers to a <TT>std::type_info</TT> object representing the
cv-unqualified type.</INS> [<I>Example:</I>...
