wondering why change connect host arg oder, while this will break all code not using keyword but postion arguments.

Oh, that's my fault. I should made all arguments keyword-only.

don't really understand what you mean by "all arguments keyword-only", I think lattest code still can pass position arguments by connect('localhost','user','pass')

Yes, and it's my fault. I had to forbid it when changing arguments order.
