Example of specialization that is erroneously rejected.
I believe that specialization of a variadic template template parameter based
on the number of template arguments is valid (see the attached code sample and
this SO question:
<a href="http://stackoverflow.com/questions/9772264/specializing-a-variadic-template-template-parameter-on-the-minimum-number-of-arg">http://stackoverflow.com/questions/9772264/specializing-a-variadic-template-template-parameter-on-the-minimum-number-of-arg</a>).
The sample attached successfully compiles under g++-4.8 but is rejected by
clang++-3.5.</pre>
