Examining that definition, I find that it is circular.  Namely, the
square-bracket notations are defined in terms of the "Char" nonterminal, which
is in turn defined in terms of square-bracket notations.  I hope we don't
choose to knowingly appeal to a circular definition.  I think we *can* do it
better.
