A template for method forwarding?

Why use stringof when you have an alias? This works for me in D1 - if you
discount default arguments and parameter storage classes (will templates
ever be able to touch these?).

template Forward(string clName, Methods...) {
    static if(Methods.length == 1) {
        mixin ForwardImpl!(clName, Methods[0]);
    } else {
        mixin ForwardImpl!(clName, Methods[0]);
        mixin Forward!(clName, Methods[1..$]);
    }
}

template ForwardImpl(string clName, string method) {
    private mixin("alias ParameterTypeTuple!(" ~ clName ~ "."
                  ~ method ~ ") params;");
    private mixin("alias ReturnType!(" ~ clName ~ "."
                  ~ method ~ ") retType;");

    mixin("retType " ~ method ~
        "(params args){ return " ~ clName ~ "."
        ~ method ~ "(args); }");
}
