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 , 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
        constructor}s such as {array}s or {record}s.  {Iteration} is
        simulated with 'is current' and 'fby' (concatenation of
        sequences).  Higher-order functions are implemented using pure
        dataflow and no closures or heaps.
