Nope, you're supposed to get a dir structure. When I call create-dir with a full path, I get a struct with a full path symbol inside. But when I call create-dir with just the folder name, the struct only contains the folder name. Maybe that explains the confusion with the exercises? But! create-dir does not return a Dir.v3 as section 20.3 says.
