A family of dataflow languages descended from ISWIM, lazy but first-order.

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.

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.
