As long as we're going to break everyone's code, list.sort(f) should also be
redefined then so that f returns a Boolean, f(a, b) meaning a is less than
b.  list.sort()'s implementation uses only less-than already, and it seems
that all newcomers to Python who didn't come by way of C or Perl (same thing
in this respect <wink>) expect sort's comparison function to work that way.
