[swift-evolution] [Draft] Allow trailing commas in argument lists

[Антон Жилин]

-1

Trailing commas look urgly to me. We should not just borrow everything from
C-family. I believe, there is a better way out.

Separation by whitespace, on the other hand, seems interesting:

sayHello(to: "John" and: "Jack")

Can be used for multiline calls, as well as dense argument passing:

[1 2 3 4 5]
