Oh, a kindred spirit. I also love single-letter variables where they make sense. I have a math-heavy background, so they're totally cool for me, BUT I get why most programmers would hate 'em. I also like them since they were the "norm" in old C# LINQ code where I learned functional programming. If I were alone in the programming world I would have written the example above with single letter vars.

I agree with your remarks, there's no right or wrong, it's like tabs and spaces.

Btw I'm also not smart enough for Haskell, but it hasn't stopped me so far ;)
