I'm not so sure anymore. Do you really think that for instance passing 
in a negative _from_ in QString::indexOf to search from the back of the 
string is intuitive API? I don't. I would rather have a specific 
indexOfBackwards or something like that. Or one could just use the 
iterator API with a standard algorithm I guess.
