It's also important to note that the errors reported can become less and
less meaningful the further you go from the first error, because the
parser has more and more trouble figuring out what the context was
supposed to be.  You can see the same thing with C or C++ compilers,
where usually only the first two or three error messages are useful.


All the best,
