You can also get rid of the parentheses like this:
thing n = n + fromIntegral $ round $ sqrt n
I'm having a hard time finding an explanation of the dollar signs. What do they do? It looks like they break up the left-ro-right association of function names to arguments. As a beginner, I love how Haskell is filled with so many good ideas, in many areas. The basic concept of functional programming is good, but also Haskell has beautiful syntax that's just pleasing to look at, and also has many convenient features which may not quite qualify as "beautiful" or "elegant" but are just convenient (still a worthy thing). Languages that borrow from Haskell, like Python's list comprehensions, invariably are much dumbed-down implementations. In Python, list comprehensions don't have guards or pattern matching. (Technically you can put in a guard via an if statement, but you are doing a lot more typing at that point.) Thanks, Mike
