For that matter, PASCAL has had variant records (i.e. sum types) since the 1970s.

Did it have an ergonomic way to exhaustively match on all the variants? Since the 70s?

How does the ABI work? If a library adds a new constructor, but I am still linking against the old version, I imagine that it could be reading the wrong fields, since the constructor it's reading is now at a different index?
