[colket, `:^`, %clkt](#clkt)
============================
Tuple of four
`:^` is a synthetic rune that produces a cell `[p q r s]`.
Produces
--------
Twig: `[%clkt p=twig q=twig r=twig s=twig]`
Sample
------
`p` is a [twig](). `q` is a [twig](). `r` is a [twig](). `s` is a
[twig]().
Tall form
---------
Kingside:
:^ p
q
r
s
Queenside:
:^ p q
r
s
:^ p q r
s
Wide form
---------
:^(p q r s)
Irregular form
--------------
undefined
Examples
--------
/~zod/try=> :^(1 2 3 4)
[1 2 3 4]
/~zod/try=> :^ 5 6
7
8
[5 6 7 8]
This is the most straightforward case of `:^`, producing a tuple of four
values in both tall and wide form.
/~zod/try=>
:^ (add 2 4) (add 2 6)
|- (div 4 2)
~
[6 8 2 ~]
Most commonly `:^` helps to organize code, allowing you to produce a
cell from nested computation.
