<pre>The following code compiles successfully on Clang trunk, but it is invalid
according to the C++14 standard:
int main() {
struct foo { template <typename ...> using nested = void; };
}
The relevant part of the standard is in [temp.mem], ยง14.5.2/2:
A local class of non-closure type shall not have member templates.
Live example: <a href="http://melpon.org/wandbox/permlink/6iFYFG3gcgzOYftp">http://melpon.org/wandbox/permlink/6iFYFG3gcgzOYftp</a>
Surprisingly, this bug is marked as fixed in bug [16947], so I guess this
is a regression.
