Tīmeklis2016. gada 27. apr. · Lazy evaluation makes it possible to modularise software into a producer that constructs a large number of possible answers, and a consumer that chooses the appropriate one. Without it, either state has to be fully generated upfront or production and consumption have to be done in the same place. Lazy expressions are expressions that are not evaluated immediately, but are instead evaluated when the result is needed.
