Functional programming
As software becomes more and more complex, it is more and more
important to structure it well. Well-structured software is easy to write,
easy to debug, and provides a collection of modules that can be re-used
to reduce future programming costs. Conventional languages place conceptual
limits on the way problems can be modularised. Functional languages
push those limits back. In this paper we show that two features of
functional languages in particular, higher-order functions and lazy evaluation,
can contribute greatly to modularity. As examples, we manipulate
lists and trees, program several numerical algorithms, and implement
the alpha-beta heuristic (an algorithm from Artificial Intelligence used in
game-playing programs). Since modularity is the key to successful programming,
functional languages are vitally important to the real world.
