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.
