Leaks in configatron.temp

[andriytyurnikov]

We've faced an issue with configatron.temp due to unexpected side effect

  # config changes in  rspec case
  # leaked into other
 configatron.temp do
      #leaks
      configs.each { |config| configatron.origins[config.origin_id] = { app_id: '123' } }
      # doesn't leak
      # configatron.origins = configs.map { |cfg| [cfg.origin_id, { app_id: '123' }] }.to_h
      example.run
end

After skimming through source code of configatron.temp, I humbly suggest authors to consider implementation of configatron.temp with Marshal.dump and Marshal.load, which looks like straightforward solution with rather strong guarantees.
