Subject: Delcaring a foo[] method

I am trying to define a method that you call like this:

  @obj.foo[123]

I thought I knew how to do this.  I tried to setup the method like so:

  def foo[](value)
    value * 2
  end

But this gives me a syntax error right at that first brace.  I could
have sworn this worked before.  What am I doing wrong?

ruby 1.8.6
