small example that expands like 3,2,1,0 ... should be 0,1,2,3

C++11 variadic templated parameter pack expansion happens for {}-initialiser in
reversed oder. As far as I understand this, they should be expanded in order. I
am not sure if its expansion or evaluation thats out of order.... clang++ does
the correct(?) ordering.
