read() returns a tuple of values of different types.

typeof is a compile-time expression but there cannot be a consistent 
result to that expression when i is not known at compile-time.

You might try using a 'static foreach' but this time Size is not a 
compile-time expression:

     static foreach(i; 0 .. Size) {
         typeof(read()[i]) Datacol;

Error: variable Size cannot be read at compile time
