[anonfunction]

Conway's Game of Life in Q:

    life:{3=a-x*4=a:2(sum -1 0 1 rotate\:,’/)/x}

[abraae → anonfunction]

By comparison in APL:

  life←{↑1 ⍵∨.∧3 4=+/,¯1 0 1∘.⊖¯1 0 1∘.⌽⊂⍵}

[LfLxfxxLxfxx → abraae]

  life←{≢⍸⍵}⌺3 3∊¨3+0,¨⊢

[RodgerTheGreat → LfLxfxxLxfxx]

I think I've nearly convinced Arthur to include an equivalent to "stencil" in k7. Fingers crossed!

[Avshalom → RodgerTheGreat]

K's approach of arrays of arrays would preclude an efficient 2d stencil operation wouldn't it?
