How can I break a long ruby hash into multi-lines? -

i have hash:

  arr={ [0,1]=>[0,0,1,1], [0,2]=>[0,1,0,1], [0,3]=>[0,1,1,0], [1,2]=>[1,0,0,1], [1,3] =>[1,0,1,0], [2,3] => [1,1,0,0] }

and want split on 2 lines quite long, @ 121 characters. i'm not sticker line length guide line 80 , longer prefer

so tried

  arr={ [0,1] => [0,0,1,1], [0,2] => [0,1,0,1], [0,3] => [0,1,1,0] }   arr.merge({[1,2] => [1,0,0,1], [1,3] => [1,0,1,0], [2,3] => [1,1,0,0]})

but tests fail with errors like

undefined method `[]' nil:nilclass

how can better break up? 1 option line continuation \ didn't particularly neat.

arr={ [0,1]=>[0,0,1,1], [0,2]=>[0,1,0,1], [0,3]=>[0,1,1,0], \ [1,2]=>[1,0,0,1], [1,3] =>[1,0,1,0], [2,3] => [1,1,0,0] }

although guess do

arr={ [0,1]=>[0,0,1,1], [0,2]=>[0,1,0,1], [0,3]=>[0,1,1,0], \       [1,2]=>[1,0,0,1], [1,3] =>[1,0,1,0], [2,3] => [1,1,0,0] }

but looks w whitespace maintenance smell indentation.

are there neater options?

arr = {   [0,1] => [0,0,1,1], [0,2] => [0,1,0,1], [0,3] => [0,1,1,0],   [1,2] => [1,0,0,1], [1,3] => [1,0,1,0], [2,3] => [1,1,0,0] }
