Ruby alias problem

ruby-talk
1

I have a class like this:

class Control
  attr_accessor :name, :parent, :children
  alias [] getChild

  def initialize(name)
    self.name = name
    @children = Hash.new
  end

  def addChild(child)
    child.parent = self
    @children[child.name] = child
  end

  def getChild(name)
    @children[name]
  end
end

So i want to alias method named getChild as []. But Ruby says "undefined
method `getChild' for class `Control'". How can I make such alias?

Locate the alias specification after "getChild" has been defined.
