Do you consider "map" to be iteration?

Jay> For example, I'd like to create a slice out of the 2nd element of each

Jay> @a = ([1,2],[3,4],[5,6]);

Jay> print join @a[][1],"\n";  # doesn't work
Jay> print join @a[0..2][1],"\n"; #doesn't work

my @a = ([1,2],[3,4],[5,6]);
my @result = map $_->[1], @a;
print "@result\n";
