Let me throw this idea here:


struct Config
{
        string title;
        int width;
}

struct Window
{
        this(Config config)
        {
                //use static foreach magic to set everything :P
        }
}

auto NewWindow( alias code )()
{
        mixin("Config config = {"~code~"};");
        return Window(config);
}

//usage:
auto a = NewWindow!q{ title : "MainTitle" };
auto b = NewWindow!q{ title : "MainTitle", width : 800 };
auto c = NewWindow!q{ width : 1000 };
auto d = NewWindow!q{};

Oh that's interesting!
