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 <wwadge@csr.uvic.ca>, 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.
