I'm trying to detect parse errors in a happy GLR grammar, but I can't!
I insert the special "token" 'error', and call the error function when
an error is found. However, the program prints no error messages, and
simply returns a ParseError at the end. Does any of you have an good
example of a GLR parser with error detection and, if possible, error
recovery as well?
