ReturnType!Fn[0] tries to give you the 0th field of the tuple,
but as the error message indicates, you can't do that without
an instance. What you want is the *type* of the field, as given
by typeof:
typeof(ReturnType!Fn[0]) Dcol;
This can be made a bit simpler by noticing that ReturnType is
unnecessary here:
typeof(Fn()[0]) Dcol;
However, if Fn() takes a bunch of complex parameters, this
might not actually be simpler.
