Definition: A function that takes no arguments.
Also known as nullary function.
See also constant function, unary function, binary function, n-ary function.
Note: Pronounced "zero-airy". By analogy to unary, binary, etc.
A 0-ary or nullary function that is pure (no state or interactions with external variables) must be a constant function.
