I don't know the differences to Pascal. Does it have the same syntax for 
variant records?

Of course it would be. But how should it work? Setting the tag variable 
when assigning a value and raising an error when reading with different 
variant? Then what if the tag variable is changed directly? Or should it 
be readonly (which would make sense IMHO).
