AFAIK *variant* records (currently) can not be replaced by something 
else. OTOH it should be no problem to allow for variant parts in other 
structured types, delimited e.g. by a visibility keyword. Variant parts 
should not prevent inheritance, only tricky typecasts, with "open-ended" 
arrays at the end of an record, then have to be handled with more care 
by the coder.
