which actually suggests a shorter, clearer way to do it:
s = s.after('X').after('X')
And the corresponding 'before' method, of course, such that if sep in s:
s.before(sep), sep, s.after(sep) == s.partition(sep)
Technically, these should probably be before_first and after_first, with
the corresponding before_last and after_last corresponding to rpartition.
