logging stuff while debugging code was probably so annoying for the creators of Haskell, that they decided to break its purity, for the sake of productivity:

trace :: String -> a -> a
this PRINTS the string, and returns the a, but it's not marked as `String -> a -> IO a`...so compiler doesn't force you have to have to rewrite lots of code.

Chapter 9 shows a nice example of a piece of code written at the beginner level, vs the same code written by a more advanced hasketier. Nice to know!
