Ah, right you are. I was thinking of this:

Array([2]) => [2]
Array(2) => [2]
but Array(*[1,2,3]) => ArgumentError: wrong number of arguments (3 for 1)

... and yes, I left out the *.
What I was thinking of was Array[*strings]

However (I knew I'd done something like this before!):

def process_data(*strings)
  strings = *strings
  strings.each do |s|
    print s.class.to_s + " " + s.to_s + " " + "\n"
  end
end

process_data("a", "b", "c")
process_data(["a", "b", "c"])

Does what you want.
