Be careful with strings.  Array() may not do what you want depending on
your target ruby:

  irb(main):001:0> RUBY_VERSION
  =3D> "1.9.2"
  irb(main):002:0> Array("hello\nworld").length
  =3D> 1
  irb(main):003:0>

  >> RUBY_VERSION
  =3D> "1.8.7"
  >> Array("hello\nworld").length
  =3D> 2
  >>

Depending on your inputs, you may need to check for a String.
