Cool - I didn't know there was a new version.
That will be interesting to see if that breaks any of
my code. But it isn't in the Debian repos so probably
you compiled it yourself, ay?

Anyhow, that function name ends with a "p" so it is
a unary function which returns a boolean, I take it.
So why doesn't it work to do just as you suggested
with `sort-subr' with that as the third optional
argument, namely PREDICATE?
