Yes, but that's OK; that's what I'm proposing. That is, I'm proposing that
if a user wants to use the new syntax extensions, the user also must put ';'
at the end of each rule.
It's OK to require ';' for new grammars. Omitting ';' has been deprecated
for many years, and no new grammars should be omitting ';'.
