....its arguments, s and i, nearly all of the elements of s could be undefined and fetch would still return a value; the only requirement is that s, i and the ith element of s are all defined. The non strict signal data structure is similar to the non strict cons described in Dataflow Architectures [2]. Although signals are non strict, the implementation does not have to be lazy. An eager evaluator computes all expressions as soon as the expression s subexpressions have been evaluated; a lazy evaluator does not perform a computation unless its result is needed by another expression. Lazy ....
