Visual Studio "intellisense" has always been pretty good for me. Seemed to make good guesses about my intentions without doing anything wild. It seemed to use ad hoc rules and patterns, but it worked and then got out of the way.

Then it got worse a couple of years ago when they tried some early-stage AI approach. I turned it off. I expect that next time I update VS it'll have got substantially worse and it will have removed the option for me to disable it.
