Sorry, Hyman, but Ada has a very specific meaning for "unspecified result",
and that's what people here (usually) mean. "Unspecified" means not only is
*any* result allowed, but also that the implementer doesn't even need to
tell you what the result will be. "Implementation-Defined" is that any
result is allowed, but the implementer has to tell you which it is.

This case is "only" about a (usually small, often a singleton) set of
allowed results. In your example, returning "-2" isn't allowed (obviously).

I realize you are using the term informally, but I think you're confusing a
lot of people by using it.

                  Randy.
