Lazy evaluation The benefits of lazy evaluation include: Performance increases by avoiding needless calculations, and error conditions in evaluating compound expressionsThe ability to construct potentially infinite data structuresThe ability to define control flow (structures) as abstractions instead of primitives Lazy evaluation is often combined with memoization, as described in Jon Bentley's Writing Efficient Programs.[4] After a function's value is computed for that parameter or set of parameters, the result is stored in a lookup table that is indexed by the values of those parameters; the next time the function is called, the table is consulted to determine whether the result for that combination of parameter values is already available. If so, the stored result is simply returned.
