## Usage

  def initialize(str)
    @str = str
  end
  
  def test
    case @str
    when string?
      puts "success"
    else
      raise "on no"
    end
  end
end

example = Example.new("test")
example.test

# irb> success
# irb> nil

example = Example.new(123)
example.test

# irb> RuntimeError(oh no)
```
