This is not a big problem because people can pick up the new E-BNFs quite
easily. If people implemented software by directly pasting the BNF into a
parser generator then that would be a bigger deal. Perhaps in the future
we will standardize EBNF and people will generate grammars directly. The
problem, of course, is that the EBNF in the standard is not optimized for
your parser generator's algorithm (and may not even be compatible with
it!). Standardizing EBNF would require a standardization of the underlying
