This looks very similar to CWG778. See also
https://github.com/llvm/llvm-project/issues/214757, GCC also incorrectly
accepts:
template<typename...T,T...>void foo(){}
int main(){
foo();
}
Though I think this is also ill-formed because there is no way to deduce the
second pack, GCC does not appear to enforce that either.
