In John Colvin's solution, should

     alias TransformMembers(alias TypeTransform, alias 
NameTransform, T) = Tuple!(
         RoundRobin!(Pack!(staticMap!(TypeTransform, 
FieldTypeTuple!PriceBar)),
                     Pack!(staticMap!(NameTransform, 
FieldNameTuple!PriceBar))));

read

     alias TransformMembers(alias TypeTransform, alias 
NameTransform, T) = Tuple!(
         RoundRobin!(Pack!(staticMap!(TypeTransform, 
FieldTypeTuple!T)),
                     Pack!(staticMap!(NameTransform, 
FieldNameTuple!T))));
