I think it is valid.  It should be considered equivalent to:

  template int, typename... T void foo(T... x);

Looks like the generic parameter pack 'auto...' is replacing the template
argument list rather than extending it.  I'll look into it.

Turns out the base template parameter index was not been initialized correctly
so it was trying to convert the 'int' parameter to a pack as well as the
invented template parameter generated for the 'auto'.  See
