opDispatch is grand!

[so]

Because i made a mistake!

struct vector(T, uint N) {
	auto opDispatch(string s) const {
		static if(N>0 && ("x"==s || "r"==s)) return v_[0];
		static if(N>1 && ("y"==s || "g"==s)) return v_[1];
		static if(N>2 && ("z"==s || "b"==s)) return v_[2];
		static if(N>3 && ("w"==s || "a"==s)) return v_[3];
		static assert("boom!");
	}
private:
	T[N] v_;
}

Better...
