Maybe, but I don't like returning junctures in those cases unless you
*explicitly* ask for it. I'd rather the default be the arbitrary lists
returned, or whatever fits the context. How about
@ar=[a..z];
%hash=(a=>1,b=>4,c=>7);
$j=1|2|3;
$k="a"|"c";
@u = @ar[$j]; # (b..d)
%u = @ar[$j].kv; # (1=>'b',2=>'c',3=>'d')
$u = @ar[$j]; # \(b..d)
$ju = juncture @ar[$j]; # 'b'|'c'|'d'
@v = %hash{$k}; # (1,7)
%v = %hash{$k}.kv; # (a=>1,c=>7)
$v = %hash{$k}; # \(1,7)
$jv = juncture %hash{$k}; # 1|7
Am I way off base here?
