I think there is a little assumption of this sometimes. Like for example, the question can become, is good software design and coding practice more advantageous than using Haskell? If you're going to spend time and energy in a mechanism to improve your code base and the quality of your application, should you try Haskell? Or some other mechanism more focused on better design? Or put it some other way, if I have many problems, and one of them is I'm not currently writing the clearest simplest easiest to read and test code, and I don't spend a lot of time on design or don't know much about it. And then I encounter an Haskell evangelist, I will very likely assume that Haskell will make me a better coder and designer, and that the language will force me into good design and safer code.
