In the spirit of, "People will try it": val one = list
.collect: case x =>
(x, x + 1)
.toMapMaybe it's enough to detect arrow at EOL. (Edit: "People will already have used it.") Edit: actually, the SIP isn't very plain on this point, but the PR includes a test that case expr is multiline. This is OK: val two = list
.collect: x => (x, x + 1)
.toMapThere is no misalignment warning. |
