That seems sensible to me.  However, if we do get stuck with a
"comparison function", then sorting may not be quite as smooth (the
cf would need to be called for each comparison); it might be better
to be able to get something suitable for passing to key=  -- i.e., the
equivalent of C's strxfrm(), rather than of strcoll(), if one had to choose.
