Why functional programming matters - per Hughes

Abstract

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.

    Actually I just stumbled upon a video recording from a discussion panel that happened during last GeeCON. From video description:

    Amongst the questions that attendees should anticipate get answers to could be: Why should I consider functional programming languages for my projects? Should I mix and match Java with other languages? What are the most-suited use cases for functional languages? Where would be an introductory area for introducing a functional language in a project? What tools should I get familiar with to get up to speed with functional programming on JVM?
