I don't know, but ADA reportedly does.
I don't know the differences to Pascal. Does it have the same syntax
for variant records?
FWIW, here is a link to the BNF of the Ada Programming Language:

Such a feature definitely seems useful to me.
Of course it would be. But how should it work? Setting the tag

with different variant? Then what if the tag variable is changed
directly? Or should it be readonly (which would make sense IMHO).
