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: calculate-all.rb
    path of file: ./repos/calculate-all/lib
    
    the code of the file until where you have to start completion: require 'calculate-all/version'
require 'calculate-all/helpers'
require 'calculate-all/querying'

module CalculateAll
  # Method to aggregate 
    
  def calculate_all(*function_aliases, **functions, &block)

    # If only one function_alias is given, the result can be just a single value
    # So return [{ cash: 3 }] instead of [{ cash: { count: 3 }}]
    if function_aliases.size == 1 && functions == {}
      return_plain_values = true
    end
