Subject: Unary operator

Hi all,

here is a novice's question: I am wondering how to equip a class with
a unary operator. Defining a method "-" like this

class Something
  # ...

  def -
    # some code
  end

  # ...
end

I have to call "-" by writing
  somethingelse = something.-

Is there a possibility to write this in prefix notation?
  somethingelse = -something

Thanks in advance, best,

Stephan
