Subject: how to add an iterator to a class?

I have a simple class (this is just an example, so ignore any syntax or
style errors):

class MyArray
    def initialize
        @a = Array.new
    end
    def Push( item )
        @a.push( item )
    end
    def GetArray
        return @a
    end
end

And I have this code:

myarray = MyArray.new
myarray.Push( 1 )
myarray.Push( 2 )

myarray.GetArray.each do | i |
    puts i
end

So my question is: How do I replace GetArray with something more elegant,
that gives MyArray a method named .each that I can call directly?
