Can a thor script can invoke itself

Question

I'm trying to figure whether it is possible for thor to invoke itself

Assuming like this

#! /usr/bin/env ruby
require 'bundler'
Bundler.require
require 'optparse'


class Thrasher < Thor
  include Thor::Actions

  def self.source_root
    File.dirname(__FILE__)
  end

  def thrash
    say 'something over here'
  end
end

Thrasher.start thrash

Can I achieve this in any way in thor, backtick and system command are available but can I do it purely via thor way.
