Why was "tantrum" trending last week?
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.
