There are those of us who respect the 80-character line and break
expressions across lines:
let x = [
NSVeryVeryVeryLongType
.veryVeryVeryLongProperty +
NSVeryVeryVeryLongType2
.veryVeryVeryLongProperty2,
]
It would be a pleasant surprise if a grammar with optional commas can avoid
blowing up existing code; I'm quite doubtful.
