I'm open to other name suggestions for the three styles.

Example sentence given: "They will be in town from March 24 through May 7". Commonly, English speakers often refer to the numbers "1 through 10", which refers to [1, 10].

While the naming today seems pretty obvious to me, I would absolutely have to frequently refer to documentation if the proposed changes were accepted. The changes proposed don't seem to match the semantics of words used every day to describe ranges.
