That bit me quite badly recently in OpenToken too. Recognition of
negative literals had to be removed to support programming languages,
but that broke existing code for simpler languages. We eventually had to
add support for negative literals as an option. The header comments may
be enlightening:

  -- One would probably want to disallow signs in languages that use '-'
or
  -- '+' as an operator between integers. If your syntax does not have
such a
  -- concept, you will probably want to allow them.
