the default should be sort by key since that is used way more often than
sort by value. well, at least it seems that way to me. but if you use a
key description sort it may be trivial either way. something like
(broken p6):

        @pairs.sort( .key ) ;
        @pairs.sort ;           # same thing if key is the default
        @pairs.sort( .val ) ;

or even using the single letter method names (i dunno what is supported

        @sorted = @pairs.sort(.k) ;
        @sorted = @pairs.sort(.v) ;

and if i am correct, no assignment would mean in-place sorting which is

so you could default to sorting pairs by keys and not bother too many.
