Right, Georg's example would be unintuitive given the current behavior
of str.split which will happily provide zero-width matches when it hits
separators in sequence.

Perl bypasses the issue by having split
(http://perldoc.perl.org/functions/split.html) take a regex; I've only
rarely used this for complex matches, though. I tried a Google code
search for

    lang:perl split\(?\s?\/\[        (simple multiple separators)
    lang:python \.splitlines\s?\(
    lang:python \.split\s?\(

but the number of results seems to oscillate between 300 and 100000, so
that didn't help much.
