=2E . . and if you want to split it into only two elements even if there
are multiple instance of the split substring, use the optional limit
argument:

    >> ary =3D "I want this - not that - nor the other.".split(' - ', 2)
    =3D> ["I want this", "not that - nor the other."]
    >> ary[0]
    =3D> "I want this"
    >> ary[1]
    =3D> "not that - nor the other."
