Is there any prettier or cleaner way to write

x = [x] unless x.is_a?(Array)

x = [x].flatten

Although I suspect the x = Array(x) method would be faster.

Yeah, but those are a little different, too...

x = [[1, 2, 3], [1, 2]]
p x.flatten

=> [1, 2, 3, 1, 2]

x = [[1, 2, 3], [1, 2]]
p Array(x)

=> [[1, 2, 3], [1, 2]]
