C++11 non-type template parameter bundle expansion

While working with C++11 template parameter bundles, I came up with the code below: ``` #include <cstdio> static void testFunc(int i1, int i2) { printf("testFunc(%d, %d)\n", i1, i2); } template <size_t... Indices> void wrapper() { testFunc(Indices...); } int main(int argc, char *argv[]) { wrapper<1, 2>(); return 0; } ``` An attempt to compile this with g++4.8.2 resulted in a `"too few arguments to function ‘void testFunc(int, int)’"` error. Is this no valid C++ or does g++ just not yet implement this kind of non-type template parameter bundle usage?
