what you (and all) think about wildcarded puns:

data Command = Command {
    cmd_name                 :: !String             
  , cmd_arcspec              ::  String             
  , cmd_arclist              ::  [FilePath]         
  , cmd_arcname              ::  FilePath           
  , cmd_arc_filter           :: !(FileInfo -> Bool) 
  , cmd_filespecs            :: ![String]           
  , cmd_added_arcnames       :: !(IO [FilePath])    
  , cmd_diskfiles            :: !(IO [FileInfo])    
  , cmd_subcommand           :: !Bool               
....
}

process_cmd (Command{*}) = do
   print cmd_name
   ...

because Haskell encourage using of structure name as part of field's
name, this will not create mess (at least for my programs), it will
work like Pascal's 'with' operator
