class ArchiveFile
  def initialize(filename)
    if not File.stat(filename).file?
      raise "#{filename} is not a valid file"
    end
  end
end

The return of #initialize is ignored. #initialize is called by #new,
and #new returns only the created object, not the return from
#initialize.

BTW, there are already packages that handle tar and zip files.
