colket, :^, %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.
