LUCID

   1. Early query language, ca. 1965, System Development Corp,
   Santa Monica, CA.  [Sammet 1969, p.701].

   2. A family of dataflow languages descended from {ISWIM},
   {lazy} but {first-order}.

   Ashcroft & Wadge <[email protected]>, 1981.

   They use a dynamic {demand driven} model.  Statements are
   regarded as equations defining a network of processors and
   communication lines, through which the data flows.  Every data
   object is thought of as an infinite {stream} of simple values,
   every function as a {filter}.  Lucid has no {data
   constructors} such as {arrays} or {records}.  {Iteration} is
   simulated with 'is current' and 'fby' (concatenation of
   sequences).  Higher-order functions are implemented using pure
   dataflow and no closures or heaps.
