Thanks for the PR! However, I probably won't merge it, I'm trying to take a more conservative stand on non-essential functionality, at least while I'm doing a lot of code cleanup 😊. It should be possible to provide this functionality by extending Client and ReqUrl manually, though. If you provided that as an example instead, then I'll probably redecide 😉

Well, I'm sorry for the late of my answer.

I'm not sure it's possible to provide this as an example with changing anything in the base code, because it needs to change Client attributes before the end of its __init__ method. For example, it's not possible to change the self._session attribute, but it's mandatory to set the new proxies.

Else, it's possible to create a class which inherit from Client and overrides its __init__ method, but it won't work anymore if you plan to rewrite it and change the way it works in your future code cleanup.

Yeah, I can see that. I think I'll keep this PR open until we reach v2, where we can then discuss how this can be implemented (the code in __init__ will probably be restructured in such a fasion that this change will be possible)
