Returns a hash table which is like a normal 'M3CHash.Table' but already
contains entries of type 'Id' for all the reserved words. Thus looking up
a reserved word in this table will return an object of type 'Id'; 'Token' can
then be used to return the reserved word token.
If 'Id' is used as a supertype e.g.
MyId = M3CReservedWord.Id OBJECT ... END;
then when an object of type 'MyId' is allocated it will be set up specially so
that 'Token(myId)' will return 'M3CToken.T.Identifier'
END M3CReservedWord.
