void main() {
    import std.typecons: Tuple, Nullable;
    import std.traits: TemplateArgsOf;
    alias NT = Nullable!(Tuple!int);
    alias T = TemplateArgsOf!NT[0];
    pragma(msg, T);                           // Tuple!int
    alias I1 = T.Types[0];
    pragma(msg, I1);                          // int
    alias I2 = TemplateArgsOf!NT[0].Types[0]; // error
    pragma(msg, I2);
}
