DEC Pascal triggers exceptions when constraints are violated, and
catching them is done in a vendor-specific manner.  I would assume
the discussion is not limited to standard-based implementations,
because then we would not be talking about who originate the concept
but rather whose committee was quickest to adopt research.

V1 of DEC Pascal, however, was from a different codebase than the V5.?
