Onion, or Array Onion, allows peeling an array like an onion. It shreds  
one layer after another, from the outer inwards the inner nested array,  
according to the given depth. Infinite depth (or greater than current  
nested array depth) is equivalent to Array#flatten.

Vote if you would like Onion for Hashes as well.

[1, [2, [3, [4, 5]]]].peel\_until(4) =\> [1, [2, [3, [4, 5]]]]

[1, [2, [3, 4], 5]].peel(1) =\> [1, 2, [3, 4], 5]  
[1, [2, [3, 4], 5]].peel(2) =\> [1, 2, 3, 4, 5]

[1, [2, [3, [4, 5]]]].peel(1) =\> [1, 2, [3, [4, 5]]]  
[1, [2, [3, [4, 5]]]].peel(2) =\> [1, 2, 3, [4, 5]]  
[1, [2, [3, [4, 5]]]].peel(3) =\> [1, 2, 3, 4, 5]
