I need to sort the result of bagof/3 according to a user-supplied function.
I thought of something like the Java function "sort(List,Comparator)" in
java.util.Collections, e.g., a predicate sort/3 with 
sort(+Comparator,+Random,-Sorted).  I did not find anything similar in the
Referendce Manual.

Can you suggest me some code that I could reuse?

Thank you,

Ulrich
