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: lookup_spec.rb
    path of file: ./repos/puppet/spec/unit/functions
    
    the code of the file until where you have to start completion: require 'spec_helper'
require 'puppet_spec/compiler'
require 'puppet_spec/file
    
  def collect_notices(code, explain = false, &block)
    Puppet[:code] = code
    Puppet::Util::Log.with_destination(Puppet::Test::LogCollector.new(logs)) do
      scope = compiler.topscope
      scope['domain'] = 'example.com'
      scope_additions.each_pair { |k, v| scope[k] = v }
      if explain
        begin
          invocation_with_explain.lookup('dummy', nil) do
            if block_given?
              compiler.compile { |catalog| block.call(compiler.topscope); catalog }
            else
              compiler.compile
            end
          end
        rescue RuntimeError => e
          invocation_with_explain.report_text { e.message }
        end
