    Metadata details:
    filename: reload_classes.rb

    def with_class_reloading(&block)
      begin
        yield
      rescue ArgumentError => e
        if(name = e.message.scan(/(can't find const|undefined class\/module) ([\w\:]+)/)
    
    def with_class_reloading(&block)
      begin
        yield
      rescue ArgumentError => e
        if(name = e.message.scan(/(can't find const|undefined class\/module) ([\w\:]+)/).try(:first).try(:[], 1))
          eval name.gsub(/\:+$/, '')
          retry
        else
          raise e
        end
