Re: [Gm2] variant records and repeated names

[Martin Kalbfuß]

A small example:

TYPE testType = (variant1, variant2, variant3);

     test = RECORD;
        shared : INTEGER;
        CASE type : testType OF
        variant1:
           a : INTEGER;
           b : INTEGER |
        variant2:
           b : INTEGER;
           c : INTEGER |
        variant3:
           a : INTEGER;
           c : INTEGER;
        END;
     END;

compiler reports an error because the names a, b and c are present
multiple times inside the record. But they are in different variants. So
I assume this should be OK.
