create an aliased type that keeps its name in error messages.

Nice. Interestingly, the error message references the wrong type 
when trying to access static members:

struct MT {
    int _payload;
    alias _payload this;
}

unittest {
    MT a;
    a.foo = 3;  // Error: no property foo for type MT
    MT.foo = 3; // Error: no property foo for type int
}
