That's difficult for me to use to fix the grammar in the spec.  If specific
errors in the grammar could be pointed out, that would be helpful.

The intention was to always match quoted terminal symbols rather than the named
terminal symbols, not just for identifier.  I've mentioned that now:

The "other" terminal symbol is meant to match any text that isn't one of the
quoted terminals or float/integer/etc.  So I think it needs to match any
character except for any character that could possibly match the other named

I don't think we want to leave out "other" from Other.

Please reopen if I've misunderstood.
