Relation To Lazy Evaluation
Lazy futures, where the computation of the future's value starts when the value is first needed, are closely related to lazy evaluation. However, the term lazy evaluation is most often used to refer to an evaluation strategy for all computation in a language, whereas lazy futures represent specific values that are computed lazily, even in a language where computation is normally strict or eager. In C++11 such lazy futures can be created by passing the std::launch::sync launch policy to std::async, along with the function to compute the value.

Famous quotes containing the words relation to, relation, lazy and/or evaluation:
“There is the falsely mystical view of art that assumes a kind of supernatural inspiration, a possession by universal forces unrelated to questions of power and privilege or the artist’s relation to bread and blood. In this view, the channel of art can only become clogged and misdirected by the artist’s concern with merely temporary and local disturbances. The song is higher than the struggle.”
—Adrienne Rich (b. 1929)
“To criticize is to appreciate, to appropriate, to take intellectual possession, to establish in fine a relation with the criticized thing and to make it one’s own.”
—Henry James (1843–1916)
“The dreary flies, lazy and casual,
Stick to the ceiling, buzz along the wall.
O heart, the spider shuffles from the mould
Weaving, between the pinks and grapes, his pall.”
—Allen Tate (1899–1979)
“Good critical writing is measured by the perception and evaluation of the subject; bad critical writing by the necessity of maintaining the professional standing of the critic.”
—Raymond Chandler (1888–1959)
