junctions as indicies

[David Christensen]

I'm looking in S09, and reading about junctions.  It seems to me that 
if we have a junction $j which we use to index into an array or a hash, 
it should DWIM and return a junction of the corresponding values.

@ar=[1..10];
%hash=(a=>1,b=>4,c=>7);
$j=1|2|3;
$k="a"|"c";
$u = @ar[$j];       # 2|3|4
$v = %hash{$k}; # 1|7
Does this make sense to others?
