According to the bash documentation, "unset NAME[SUBSCRIPT]" destroys an array element. However, the documentation is not clear on whether elements NAME[SUBSCRIPT] are shifted down. What actually happens is that the array length is decremented and the elements are NOT shifted. With the current behavior, it is cumbersome to deal with arrays with unset elements.

For an exhausting discussion, please see Red Hat bug report #62427 (at "http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=62427";).
