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?
