Variables of tuple type can be used in assignments, but not anywhere else
(including initialization). And the error message is quite terrible.

void foo(T...)(T x) {
   T a;
   T b;
   a = x; // ok
   b = x; // ok
   T c = x; // fails
}

void main() {
   foo(1,2,3);
}

1,_param_2)) of type (int, int, int) to int
