in thread RFC:A brief tutorial on Perl's native sorting facilities.
GRT requires that you stringify (serialize) the values of the list you want to sort. That's not always possible. Eg. if it's a list of objects ...
And even if it's just a list of references to some data structures, by serialization and deserialization you end up with copies of the data structures. Which may matter a lot if you keep other references (in)to the structures.
