An integer interval that has a finite lower or upper endpoint always includes that endpoint. Therefore, the exclusion of endpoints can be explicitly denoted by writing a .. b − 1 , a + 1 .. b , or a + 1 .. b − 1. Alternate-bracket notations like [a .. b) or [a .. b[ are rarely used for integer intervals. I recall this discussion began using ".." (so should conventionally have included both endpoints) but was switched to "-" to save a character. It's only the exposed message interface I'm talking about here: I've no objection to the use of boundary-style ranges within the code.
