You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: view_helper.rb
    path of file: ./repos/super/lib/super
    
    the code of the file until where you have to start completion: # typed: true
# frozen_string_literal: true

module Super
  module Vi
    
    def classes(*list)
      result = list.map do |c|
        case c
        when String
          c
        when Array
          if c.size != 2
            Kernel.raise %(Expected exactly two elements (["class", some_condition]), got: #{c.inspect})
          end

          c.first if c.last
        end
