Please note that this is just a simple problem, with a solution of printing out the right reference cheatsheet.

The real difficulty comes (IMO) when looking at piles of symbols in code and trying to determine what kind of meaning is coming from the symbol soup (C++ and Perl are notorious for this too).

Quite often (usually?), of course, public Haskell is written in a very clear and readable style. That's a major reason to use Haskell - to write in a readable language.
