Be my guest - I'm very happy to have someone else host it, maintain it,
document it, and answer questions on it :-)

I just thought of a little improvement:

can become

       @logger_proc ||= DEFAULT_LOGGER_PROC

with that constant defined earlier in the module.

The nice thing about defining it as a module, is that you can still get
global logging by including it at the top level:

  require '/path/to/logger'
  include Logger

  log "hello world"

  class Foo
    def initialize
      log "I am a new #{self.inspect}"
    end
  end
  Foo.new
  Foo.new

This logger does what I need at the moment, but I imagine another nice
feature would be to have multiple debug levels and be able to turn logging
on or off for those levels.

Regards,

Brian.
