Thanks!

Unfortunately, return type issue is more important in my case. I'll check if implementation from ParameterStorageClassTuple can be adapted for return types though.

I think this should work:

template returnsRef(alias f)
{
    enum bool returnsRef = is(typeof(
    {
        ParameterTypeTuple!f param;
        auto ptr = &f(param);
    }));
}
