Er, the difference here is that we're given the Python code for `getUsers` but not the Haskell code for it. That makes the error in Python obvious. The incorrect `userCount` in Python looks just as obviously correct as the incorrect `userCount` in Haskell; and conversely, if we were given the code for the Haskell `getUsers` (or even just the type signature!) the error would be just as easy to spot.
