<P>The current rules for determining whether a name refers to the current
instantiation, given in 13.8.3.2 [<A href="https://wg21.link/temp.dep.type#1">temp.dep.type</A>] paragraph 1, do not
cover the case when a <I>template-id</I> matching a primary template or
partial specialization appears in the definition of a member of the
template.</P>

<P><B>Proposed resolution (August, 2010):</B></P>

<P>Change 13.8.3.2 [<A href="https://wg21.link/temp.dep.type#1">temp.dep.type</A>] paragraph 1 as follows:</P>
