Given: `let x = Optional(3)` then `let y = 5 + x ?? 2` will not compile but `let y = 5 + (x ?? 2)` will.
Should NilCoalescingPrecedence be raised? The current operator precedence chain is: BitwiseShiftPrecedence > MultiplicationPrecedence > AdditionPrecedence > RangeFormationPrecedence > CastingPrecedence > NilCoalescingPrecedence > ComparisonPrecedence > LogicalConjunctionPrecedence > LogicalDisjunctionPrecedence > TernaryPrecedence > AssignmentPrecedence > FunctionArrowPrecedence > [nothing] It seems to me that `NilCoalescingPrecedence` should probably be higher than `MultiplicationPrecedence` and possibly higher `BitwiseShiftPrecedence` as its job is to produce an unwrapped value that can then be operated upon. I think CastingPrecedence should be even higher because `expression as? T ?? fallback value` should be parsed as `(expression as? T) ?? (fallback value)` I apologize profusely because I know this is beyond last minute, -- E
