Subject: Is it ellegant to use a global variable to store a Logger object?

Hi, I use Logger class in a programm and since I need to log in lot of 
different places (into classes, into methods...) I use a global variable in 
this way:

  $log = Logger.new
  $log.debug ...

so I can use $log anywhere in the code. Is it ellegant and "the Ruby way"?

The other possibility I see is creating a class that stores the logger 
instance into a @@class_variable (@@logger) and call class method anywhere in 
the code:


  class MyLogger

    @@logger = Logger.new

    def self.debug(x)
      @@logger.debug(x)
    end

    ...
  end

  MyLogger.debug ...

Which is a more ellegant way? is there other option?

Thanks for any advice I could receive from you.
