From Read Ruby: When given an object that does not respond to :to_a,
Kernel.Array() returns an Array with that object as its sole element.
Therefore, splatting such an object causes it to expand to itself,
effectively a no‐op.

Here' the link to the splat coverage:  http://ruby.runpaint.org/variables#splat
