Backing this up: It's also worth remembering that this syntax is an edge case. The vast majority of key paths will not be ambiguous in a way that requires parentheses. Even if you think \(Foo.bar) would look better than (\Foo.bar), you should keep in mind that most of the time, you'll only need \Foo.bar, and the parenthesized syntax should be a natural extension of that. -- Brent Royal-Gordon Sent from my iPhone
