Is the new version what you had in mind? Do you want to avoid completely ignoring errors, even if `.` is on the LHS? A different variant I've been also experimenting with is to change the `Expr` type to something like `typedef std::function<uint64_t(optional<uint64_t>)> Expr;` and when evaluating `Dot` inside `getSymbolValue`, throw an error when `.` is not available.
