struct A(T...) {
alias S = T;
alias S this;
}
alias X = A!(int, double);
alias Y = X[0]; // Fine
pragma(msg, Y); // Not int ?!?!
// A!(int, double)[0] ???
Y y;
pragma(msg, typeof(y));
pragma(msg, is(typeof(y) == int)); // false ?!

No wait, so there is actually no way to index a struct with a tuple alias this?
