Right, you name it: you get *pairs* out of the array, not named
parameters. Under the proposal, a Pair object doesn't have any special
magic -- it's simply

    class Pair { has $.key; has $.value is rw }


    my @array = (42, "hi", (a => 23));
    foo [EMAIL PROTECTED];  # same as

    foo 42, "hi", (a => 23);  # three positional params (Int, Str, Pair)

But that's exactly the problem. You shouldn't have to worry about any
special magic when dealing with [EMAIL PROTECTED] Consider:

    sub foo ($a, $b, $c, ?$d) {...}

    my @array = (1, 2, (key => "value"));
    foo [EMAIL PROTECTED];  # fine, no problem, $c will receive (key => "value")

    my @array = (1, 2, (d => "value"));
    foo [EMAIL PROTECTED];  # oops! $a = 1, $d = "value"
                  # "Required argument 'c' not given!"

    my @array_of_pairs = %hash;  # short for
    my @array_of_pairs = list %hash;
