As for whether it is evaluated, I don't know without looking closely at the code, but I don't think you need to worry about that and I wouldn't recommend writing code that depends on knowing whether it's evaluated. (If you're concerned about performance, this is another case where Haskell's lazy evaluation will help.) Here's how it works: both the |
