Lost in Technopolis
As some one who has enjoyed the Lisp language (in several flavors) for about 15 years now, I wanted to express some of my reactions at recently discovering Haskell, and why it has supplanted Lisp as the apple of my eye. Perhaps it will encourage others to explore this strange, wonderful world, where it looks like some pretty damn cool ideas are starting to peek over the horizon. First, let me say

Refactoring Functional Programs
Refactoring is about `improving the design of existing code' and as such, it has been practised as long as programs have been written. The term refactoring specifically refers to a common activity in programming and software maintenance: changing the structure of a program without changing its semantics. Often, refactoring precedes a program modification or extension, bringing the program into a f

If you like, it's the same general goal as John Hughes's famous paper "Why functional programming matters".
