It doesn't seem super useful to be honest. The semantics are odd, too.
What should this do?

    shift
    set blah
    unshift

Or this?

    foo=(42)
    shift foo
    integer foo
    unshift

There is no obvious answer, only options with pros and cons. The path
from a special-purpose hack to a general solution is long and arduous.
