Sorry, that does not work ... I was inheriting an orig_new in "class 
Class" which is not shown here.

This is what I had:


class Class
  alias_method :orig_new, :new
  def new(*args,&block)
    result = orig_new(*args,&block)
    print "In Class.new"
    print " with #{args.inspect}" if args
    print " and #{block.inspect}" if block
    print "\n"
    print "\tresult.class is #{result.class}\n"
    result
  end
end

class Array

  @@count = 0

  orig_new = %s{Array.new}

  def Array.new(*args,&block)
    print "In Array.new"
    print " with #{args.inspect}" if args
    print " and #{block.inspect}" if block
    print "\n"
    print "\tself.class is #{self.class}\n"
    @@count += 1
    puts "\tcount is now #{@@count}"
    #super
    orig_new(*args,&block)
  end

  # ...

end

and I thought it was working...
