====== Functional Programming ======

Why Functional Programming (FP)?

Put quite simply, a functional style of programming can be achieved in any programming language, from //Java// to //Scala//, or pretty much any language--yet it is not the usual style that is practiced.

I do not oppose object oriented programming (and think that OO can coexist nicely with FP), rather, I believe that a style of programming that embraces the advantages of both OO and FP can realize significant benefits.  For example:

  * Easier tests with fewer fixtures and mocks, that refactor cleanly with the production code
  * More natural parallelism.  
    * Using a functional architecture, often parallelism can be added automatically as a feature of the library, without requiring synchronization or locking.
    * With multiple cores being standard equipment on today's computers, having natural parallelism that you just switch on is a huge advantage.

In this space I'll index my writings on functional programming, and particularly on Monads.
