Here's an error the Haskell run-time system might throw: *** Exception: Prelude.head: empty list (or whatever)
So now what? Action plan = [].
rgrep " head " .
Lists 17 items for three projects I've been working on summing to 10000 lines of haskell. Use listToMaybe or pattern matching and -Wall, and raise an explicit (error "with explanation"), which is all good practice in the C world as well. Please, don't make undocumented use of partial functions in serious code. You're absolutely right, and the compiler can warn the programmer for such mistakes. However, I've found that analysing the run-time behaviour/errors (if they do occur) in a Haskell program to be harder
