Yes, I was about to ask the same. It seems like all the sigil characters are taken. This is one of the reasons why I did not object to the non-sigil notation originally proposed despite the ambiguity with static properties and instance properties with the same name. But using a sigil seems like it can unify method references and key path references.
Is the single quote taken? For example: let path = 'Bag.things[0].name bag[path] bag['Bag.things[0].name] bag['.things[0].name] bag.things[0]['.name] bag.things[0]['Thing.name] And the examples on the proposal would become: 'Person.friends[0].name luke['.friends[0].name] luke.friends[0]['.name] If we were to put it between root and the path then it would look like this: let path = Bag'things[0].name bag[path] bag[Bag'things[0].name] bag['things[0].name] bag.things[0]['name] bag.things[0][Thing'name] Right now the compiler tells me that it found an "unterminated string literal". When I add the closing single quote then it tells me "single-quoted string literal found, use '"' instead" > On Mar 22, 2017, at 3:16 PM, Brent Royal-Gordon via swift-evolution > <[email protected]> wrote: > >> On Mar 22, 2017, at 9:00 AM, Vladimir.S via swift-evolution >> <[email protected] <mailto:[email protected]>> wrote: >> >> bag[#path] > > What do these do? > > bag[#file] > bag[#line] > bag[#function] > // etc. > > -- > Brent Royal-Gordon > Architechies > > _______________________________________________ > swift-evolution mailing list > [email protected] > https://lists.swift.org/mailman/listinfo/swift-evolution
