Wrapping class method

Try this:

module ActiveRecord

  class Base

    class << self
      alias old_establish_connection establish_connection
    end

    def self.establish_connection(arg)
      logger.debug("Establishing connection")
      self.old_establish_connection(arg)
    end
  end
end

Yes, that's exactly it. And it even clarifies the class << self idiom
that I've been curious about to some extent. Thanks!

Erik's metameta library looks more elegant, but also more complicated
than I'm able to understand yet. I'm trying to restrict myself to using
constructs I understand completely.
