Yeah, I went through the Coursera course. Honestly, it was amazing. I had read through several programming books, but this was systematic. The "design recipes" help you to write clean, testable functions, and to think about your design before you start typing. I actually found it to be one of the best introductions to programming in Haskell. I had read 'Learn You A Haskell', and 'Real World Haskell' but this course made the whole approach to types, and pure functions really click.

I remember two times where learning a language that didn't embed the full paradigm (ADA objects) made me understand it better (Class OOP as in Java), the other one was monads in emacs lisp, so I think I understand your point.

The design recipes felt a little bit dull at first, but for a newcomer it's probably the good rhythm anyway. And now I often 'construct' my function through stubs, tests and then full code. Kudos to the authors.
