I think much of what this cheatsheet covers really did not give me any problems when I was first learning Haskell. Most of the syntax is well-designed and intuitive: for example, list comprehensions are just like set-builder notation from math and pattern matching does exactly what it looks like. (As an aside, I think this is a good example of why syntax does matter. I learned Haskell at the same time as Scheme, with no prior functional programming experience. Haskell's pattern matching syntax made understanding complex recursion far easier than Scheme's if and cond statements.)

Much of these difficulties are also ameliorated with a good text editor (Emacs). With good syntax highlighting and indentation, it's easy to write syntactically valid code. It also really helps to be able to easily load and run GHCi.
