I'm glad it was helpful.

In general we're happy to help but it does annoy us when people make assumptions about what it's like to program in Haskell without actually trying it. If you'd like help I can suggest Haskell Reddit https://www.reddit.com/r/haskell/ or emailing me personally http://web.jaguarpaw.co.uk/~tom/contact

Only if you have very punitive assumptions about what Haskell's rules are, like those who have never used the language often do. People who actually write Haskell programs have other ideas.
