One thing you can do is bundle up parameters like this into a single parameter object, as bhelkir suggests in a comment. Haskell is so close to lambda calculus, I've been struggling to learn lambda use the organizing power of OOP and design patterns and the efficiency of FP. Design Patterns are signs of weakness in programming languages Quelques éléments de syntaxe du langage Haskell. [Haskell-cafe] Design Patterns by Gamma or equivalent. In the last tutorial we saw primitive implementations of the Reader , Writer and State patterns. For a long time, I have wanted to write a series of blogposts about Design Patterns in Haskell. Earlier we gave several examples of pattern matching in defining functions---for example length and fringe. There are two solutions, and I will use a sample program to demonstrate both of them. Haskell has been around long enough now that some design patterns have emerged. You got this backwards: what some folks call "idioms and (design) patterns" > actually *is* FP, because it is just this: higher order functions.
