Etymonline
Word Origin & History
lucid
1591, "bright, shining," from L. lucidus "light, bright, clear," from lucere "to shine," from lux (gen. lucis) "light," from PIE base *leuk- "to shine, be bright" (see light (n.)). Sense of "easy to understand" first recorded 1786. Lucid interval "period of calm or temporary
sanity" (1581) is from M.L. lucida intervalla (pl.), which was common in medieval Eng. legal documents (cf. non est compos mentis, sed gaudet lucidis intervallis).

LUCID definition
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
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.
