A language (such as Pascal, Ada, APL, or Prolog) thAT, though ostensibly general-purpose, is designed so as to enforce an author' s theory of "right programming" even though said theory is demonstrably inadequATe for systems hacking or even vanilla general-purpose programming. Often abbreviATed "B&D" thus, one may speak of things "having the B&D nATure". See Pascal. Compare languages of choice. [Jargon File] (1996-01-05)
