Getting FieldNameTuple including all base-classes.

[realhet via Digitalmars-d-learn]

Hi,

I was able to reach all the fields in a subclass using foreach 
and BaseClassesTuple, but is there a way to do this using 
functional programming primitives, but in compile time for tuples?

private template FieldNameTuple2(T) {
  enum FieldNameTuple2 = BaseClassesTuple!T.map!(S => 
FieldNameTuple!S).join;
}

This is obviously wrong, but is there a way to do it?

I've searched for FieldNameTuple and BaseClassesTuple, but 
without luck. It's weird because it seems like a common thing to 
do.

Thanks in advance!
