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

I hate to resurrect this thread, but I have a problem that I can't  
seem to solve and I didn't want to rehash the original suggestions.

I need a global Logger within a framework I wrote. The trouble is that  
I need to be able to instantiate multiple independent copies of this  
framework within the same Ruby runtime (specifically Jruby).

If I do this it doesn't work for more than one instance:

module Namespace
   Logger = # instantiate some logger

   module Submodule
       class Klass
         def foo
           Logger.log("in Klass#foo")
         end
       end
     end
end

I can load and instantiate this only once in the runtime. If I try to  
do it a second time, it's like I have reopened the class/module and  
Logger gets redefined. Each instantiation shares the same global  
Logger which is *not* what I want. I want each one to have their own  
instance.

Is this possible? Any recommendations for solving it?
