Note: Regkey and Regvalue used to maintain a distinction from the hash definition of the terms key and value.

Perhaps you want an extra step, and to have a hash of regkeys=>{...} and regvalues=>{...}. You can't have two regkeys with the same name or two regvalues with the same name, but you can have a regkey and a regvalue with the same name.

{
  'Regkeys' => {
            HKEY_CURRENT_USER => {
                   'Regkeys'=>{...},
                   'Regvalues'=>{'(default)'=>{type=>REG_SZ, value=>un
+def},
                                ...},
                   },
            HKEY_LOCAL_MACHINE => {...},
            
          },
  'Regvalues' => {'(default)'=>{type=>REG_SZ,value=>undef},
                  ...},
}
