Algebraic Data Types

Some articles on type, types, data types, algebraic data type, data, algebraic data types:

Product Type
... In programming languages and type theory, a product of types is another, compounded, type in a structure ... The "operands" of the product are types, and the structure of a product type is determined by the fixed order of the operands in the product ... An instance of a product type retains the fixed order, but otherwise may contain all possible instances of its primitive data types ...
Generalized Algebraic Data Type
... In functional programming, a generalized algebraic data type (GADT, also first-class phantom type, guarded recursive datatype, or equality-qualified type) is ... this extension, the parameters of the return type of a data constructor can be freely chosen when declaring the constructor, while for algebraic data types in Haskell 98, the ... language extends Haskell with generalized algebraic data types ...

Famous quotes containing the words types, algebraic and/or data:

    The bourgeoisie loves so-called “positive” types and novels with happy endings since they lull one into thinking that it is fine to simultaneously acquire capital and maintain one’s innocence, to be a beast and still be happy.
    Anton Pavlovich Chekhov (1860–1904)

    I have no scheme about it,—no designs on men at all; and, if I had, my mode would be to tempt them with the fruit, and not with the manure. To what end do I lead a simple life at all, pray? That I may teach others to simplify their lives?—and so all our lives be simplified merely, like an algebraic formula? Or not, rather, that I may make use of the ground I have cleared, to live more worthily and profitably?
    Henry David Thoreau (1817–1862)

    To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.
    F. Scott Fitzgerald (1896–1940)
