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.
