my int @a is shape(Int ; Int) = (1..10 ; 2..100 :by(2) ; 4);
$x = pop @a
push @a, $x;
@b = sort @a;
# etc
I see two views to take with these cases.
1) flatten the array to one dimension, and act accordingly.
or
2) assume
my int @a is shape(Int ; Int);
my @a is Array of Array of int;

I'm trying to define zip(), but can't come up with a signature for a
function that returns a lazy list of lvalues, but the list itself is not
lazy?
As a second matter, can you declare a type for the elements of a slurpy
array?
So far I have:

I did leave out some POD markup forms. Assume that, if I did not mention

I am aware of at least one program that adopts XML for
(customizable/"skinnable") GUI descriptions. This has a sense for markup
languages are typically "descriptive", i.e. they say how something IS as
opposed to, say, procedural languages that let one implement something
that DOES something[1].

Aaron,
Upon reading this, it is unclear to me whether you have read about the

used by Kwiki.
It is not the same format at all. Kwid is merely /inspired/ by Kwiki,
which in turn is inspired by the (more usenix) features of modern
