It’s a shame it’s got less opinionated in other ways. Scala developers must be really looking forward to the endless debates over curly brackets vs white space.
I still can't believe they went for that. I wouldn't really care if the team wanted to switch to significant indentation, but it's absurd to provide two altogether different syntaxes just for the sake of it.
It isn't for the sake of it, breaking source compatibility would have been a major annoyance.
I don't think i will be much of a problem. Braces are already optional in Scala2 if you only use a single expression. The change just gives you the option to be more consistent and remove braces everywhere.
