Ruby alias problem

A

Alexander Rysenko

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?
