I don't mean a constraint in the formal sense. Rather I'm talking
about the whole class of errors that are "programming mistake caused a
wrong/nonsensical value to be passed for an argument" as opposed to
errors that can legitimately happen in a non-buggy program (out of
memory, no such file, limit exceeded, invalid input, etc.). Sorry I
wasn't clear.
