> 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.

Maybe I should start to work on the support for array constructors and
operators once generic functions and dynamic packages are working... :P
