Pascal sets can only contain values/enumerations whose ordinal value is
<= 255. There are more than 256 tokens already. If you add new tokens at
the start, existing tokens may get an ordinal value > 255, so existing
set expressions that previously worked may now fail.
The only way to solve that is to remove the items whose ordinal values
are > 255 from set expressions and to test for them using the regular
