Long parameter lists usually aren't a code smell, and personal 
opinions and preferences are not enough to refute it. The 
alternative to long parameter lists is the Builder OOP pattern, 
which also usually isn't a code smell. Some records/objects just 
have many members and it doesn't make sense to split them up into 
smaller groups.
