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: context.rb
    path of file: ./repos/gitlabhq/lib/gitlab/ci/config/interpolation
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Gitlab
  module Ci
    class Config
      module Int
    
          def deep_depth(data, depth = 0)
            values = data.values.map do |value|
              if value.is_a?(Hash)
                deep_depth(value, depth + 1)
              else
                depth + 1
              end
            end
