Will Hyper operators work on strings as well ?
e.g.
('pic1','pic2','pic3') ^_ ('.jpg')
or even
my @images = qw( pic1 pic2 pic3) ^_ ('.jpg');
R.

my @images = map { $_ _ '.jpg' } qw(pic1 pic2 pic3);
Hmmm, that's visually unappealing.
Just thinking out loud.

Now that's sexay.

Is the following correct for := :
left side is like function in the respect that the right side is treated
differently depending on the left-side-types i.e. left side is like
prototype!! for the right side.
(@a ,@b) := (@b,@a)
is the same as :
(\@a, \@b) = (\@b, \@a);#if we had ref-allowed on

Doesn't that clash with the default currying argument?

When you say Unary here:

Well, "car" and "cdr" don't really fit; the key and value of a pair can be any
type of object, unlike the Lisp case where the cdr is always a list
(while the car can be either a list or an atom). But you can always
define your own accessor methods with whatever names you like. :)

Incorrect - "cdr" can be anything at all, just like

My understanding is that there won't be anything terribly magical

Yes. You can "hype" *any* operator (except ^)

Yes, indeed, they should be:

Sure. Roll-you-own with:

method car { return .key }
method cdr { return .value }
