<P>[Adopted at the February/March, 2017 meeting.]</P>

<P>
<A HREF="1059.html">Issue 1059</A> changed 6.9.5 [<A href="https://wg21.link/basic.type.qualifier#6">basic.type.qualifier</A>] paragraph 6
to read,</P>

<BLOCKQUOTE>

An array type whose elements are cv-qualified is also considered to have
the same cv-qualifications as its elements.

</BLOCKQUOTE>

<P>However, that change overlooked the earlier statement in paragraph
2,</P>

<BLOCKQUOTE>

A compound type (6.9.4 [<A href="https://wg21.link/basic.compound">basic.compound</A>]) is not cv-qualified by the
cv-qualifiers (if any) of the types from which it is compounded. Any
cv-qualifiers applied to an array type affect the array element type, not
the array type (9.3.4.5 [<A href="https://wg21.link/dcl.array">dcl.array</A>]).

</BLOCKQUOTE>

<P><B>Proposed resolution (January, 2017):</B></P>

<P>Change 6.9.5 [<A href="https://wg21.link/basic.type.qualifier#2">basic.type.qualifier</A>] paragraph 2 as follows:</P>

<BLOCKQUOTE>

A compound type (6.9.4 [<A href="https://wg21.link/basic.compound">basic.compound</A>]) is not cv-qualified by the
cv-qualifiers (if any) of the types from which it is compounded. Any
cv-qualifiers applied to an array type affect the array element type<DEL>,
not the array type</DEL> (9.3.4.5 [<A href="https://wg21.link/dcl.array">dcl.array</A>]).
