One disadvantage of the current parsing scheme is that a single parse
error prevents analysis of the rest of the buffer, which is
potentially disturbing to a user's workflow. For relatively simple
grammars such as \TabCode, it is simple enough to resynchronize at the
next token, whereas for more complex grammars the resolution is less

Our plans for Climacs go further than creating an improved
