Using tupleof, named unions are not taken into account. Anonymous unions seem
to work "just fine":

//----
import std.stdio;
import std.traits;

void main() 
{
    S s;
    writeln(s.tupleof);
    writeln(FieldTypeTuple!S.stringof);
}
//----

//----
struct S
{
    union
    {   
        int a;
        int b;
    }   
}
//Produces:
00
(int, int)
//----

//----
struct S
{
    union u
    {   
        int a;
        int b;
    }   
}
//Produces:

()
//----

This is quite bothersome, as it impacts FieldTypeTuple too.
