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: enum.rb
    path of file: ./repos/ferrocarril/mruby-sys/vendor/mruby-bc7c5d3/mrbgems/mruby-enum-ext/mrblib
    
    the code of the file until where you have to start completion: ##
# Enumerable
#
module Enumerable
  ##
  # call-seq:
  #    enum.drop(n)               -> array
  #
  # Drops first n elements from <i>enum</i>, a
    
  def take_while(&block)
    return to_enum :take_while unless block

    ary = []
    self.each do |*val|
      return ary unless block.call(*val)
      ary << val.__svalue
    end
    ary
  end
