What I've implemented here deviates from the current proposal text in the following ways: - I had to introduce a FunctionArrowPrecedence to capture the parsing of -> in expression contexts. - I found it convenient to continue to model the assignment property explicitly. - The comparison and casting operators have historically been non-associative; I have chosen to preserve that, since I don't think this proposal intended to change it. - This uses the precedence group names and higherThan/lowerThan as agreed in discussion.
