'Nice error messages' is an important goal - it is one of a few things that tends to stop people from using parser generators for 'production' compilers. Parsing itself is the easy bit, and while things like left recursion can make some things a bit easier, the workarounds are so well understood it is not what stops people. But error handling does.
