There was a problem hiding this comment.
Absolutely terrible display of the diff in GitHub. I've added two optional unwrappings which messes with the indentation, which messes up the diff. Haven't really changed that much.
I added comments highlighting the things I've actually changed/added.

Better precision in signature help. You now don't have to start typing in an argument for it to highlight. We now look at commas to decide which argument you're currently intending to fill in.
Closes #672
