I'm all for it.  I've had to implement rsplit on my own as well, and always 
lamented (but never did anything, unfortunately) about its lack in the 
standard library.  That strings have rfind, rindex, rstrip, and rjust, but 
not rsplit always seemed somewhat less than complete to me.

Python's string methods (and the fact that I can easily iterate over the 
characters in a string) enable me to write heavily string-manipulating code 
without resorting to the cryptic regular expressions my old Perl code was 
laden with.  As long as they're named appropriately, I can't see the harm in 
adding useful methods, especially one such as rsplit that completes a set of 
front-to-back/back-to-front methods.
