If I'm not mistaken this is unnecessary, as "static" (without #{...}) Regexps are created only once (because they are immutable):

    class Formatter
      def clean
        /\e\[[0-9;]*m/
      end
  
      def clean2
        />#{'a'*2}</
      end
    end

    2.times { p Formatter.new.clean.object_id }
    puts
    2.times { p Formatter.new.clean2.object_id }

Hi, Syslog::Logger should have a formatter so that it can behave similar to the regular Logger class.  I've attached a patch with tests to implement the formatter.

Thanks!
