The method exists, and it is useful when you code method that expect
various parameters, and convert them all to strings. It is not invoked
in string expansion (for reasons of optimization, I believe).

You can redefine to_s, and then explicitly invoke it, like

class String
  def to_s
    'another string'
  end
end

'test'.to_s
