Subject: class X < Hash ...  how do I do X.new { |hash, key| ...} ?

I created a child class of Hash and would like to internalize the
equivalent of Hash.new {|hash,key| }  The following code failed:

class X < Hash
  def initialize
    super { |hash,key|  ... }
  end
end

Any suggestions?  I suppose I could do it externally with a create()
wrapper but it doesn't seem very pragmatic.

def create_X
   y = X.new {|hash,key|  ... }
   return y
end

My overall goal is to record a list of attempts to read undefined Keys.

Thanks,
Larry
