This looks great.  What about the possibility of resynchronizing the
input for the next error message?  There are some methods like skipping
all input to the next, for example, closing paren or curly brace before
restarting the parse.  The purpose of these is to diagnose as many mistakes
as possible.  Does anybody have any ideas about doing this next?
