79–93	Using global variables isn't a good idea. We should use more object-oriented approach, where we have a struct with config fields and methods that use these fields. Is it possible to have something like this?

79–93	Using global variables isn't a good idea. We should use more object-oriented approach, where we have a struct with config fields and methods that use these fields. Is it possible to have something like this? This diff is abandoned in a favor of D5641 and D5642. The comment in D5329 is related to this question. The approach was changed to use a lazy static in D5641.
