I still have a hunch that editors, when attempting to assist the developer, should have memory of the last clean copy of the code and use that for inference, as much or moreso than the current code.

In particular there are no guarantees that as I am writing a new method that I have the brackets balanced to make the code around it be seen as valid code. I'm so tired of not being able to use autocomplete in the middle of a complex edit unless I ritualistically write the code in an order that is unnatural to me.

Similarly, if I'm iteratively trying to fix a type error, the previous edit was not sane, and is of no help at all. You may have to go several edits back.
