  all_args = (@args + extra_args).uniq
  options = all_args.select { |arg| arg.start_with? '-' }
  files = extra_args.select(&File.method(:exists?))
  command = (@args - options - files).first

  [command, *options, *files]
end

#run ⇒ Hash<String, Array<Astrolabe::Node>] with file => search results.

If the shortcut was defined with a single block and no extra arguments, it only runs the block and return the result of the yielded block. The block is also executed in the [Fast] module level. Making it easy to implement smalls scripts using several Fast methods. Use ARGV to catch regular arguments from command line if the block is given.
