An interval `from..through` that includes `from`, `from+step`, `from+step+step`,
etc. up to and including `through`.

In case step is positive (negative), the first value larger (smaller) than
through will not be included.

In case `step.sign = (from ⋄ through).sign`, this `Set` is empty, e.g.,
`interval 1 2 -1` and `interval 2 1 1` are both empty.
