It is worth remembering that there are checks for conditions which do not raise Constraint_Error. I actually used a Suppress for elaboration checks once. ;-) There was a call in a function body that could only occur after elaboration was complete, but the compiler couldn't find a valid elaboration order without the Suppress. It has been decades, so I can't remember the details.
On a related issue, the need for gotos seems to be limited to implementations of finite state machines (FSMs). I guess I could write a program that would generate goto-less code for deterministic FSMs, For non-deterministic FSMs, I guess the way to go would be to turn them into deterministic FSMs. Maintaining such code would be next to impossible.
