Because I'm building these classes for another API, namely Resque. I'm
creating a DSL for building Resque jobs, which the documentation defines
thusly:

Resque jobs are Ruby classes (or modules) which respond to
the perform method. Here's an example:

class Archive
  @queue = :file_serve

  def self.perform(repo_id, branch = 'master')
    repo = Repository.find(repo_id)
    repo.create_archive(branch)
  end
end


So unfortunately I can't change the form of the classes I'm trying to
generate (with the possible exception of changing them into modules)
