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.

Writing with a lucidness that borders on poetry, he argues that if the first five extinctions were due largely to natural factors such as asteroids colliding with the earth, blame for the present paroxysm of death and destruction can be laid at the doorstep of one species that has forgotten it evolved with the rest of life on this planet.

The Diversity of Life

From Ken Saro-Wiwa's experimental epistle "Africa Kills Her Sun," for example, to the pathos and humor of Bloke Modisane's story "The Dignity of Begging," the terse, pathetic humor of Ali Deb's "Three-Piece Suit," the lucidness of Tayeb Salih's "Handful of Dates," and the poignant painfulness of Henri Lopes's tale "The Advance" and Sindiwe Magona's "It Was Easter the Day I Went to Netreg," African Rhapsody chronicles a discordant recital that is not too far from the overwhelming realities of the lives of Africans today.
