I should have pointed out that this kind of problem is pretty common: regular
expression matching suffers from the same problem: when you have a regex, the
regex engine cannot tell which matching failures are errors from the point of
view of the user and which are not. If there is a good regex debugging tool, I
am not aware of its existence but, I would love to see one...
