Convert Object to Array

Have you ever been in a situation where you needed a method that does all of the following?

  • Convert nil to an empty Array, and
  • convert a non-Array variable n to [n], and
  • leave the Array variable as is.

The way to achieve this, is using the little known method Array():

Array(nil) # => []
Array([])  # => []
Array(1)   # => [1]
Array([2]) # => [2]
