[swift-evolution] [Idea] Wrap switch cases in curly braces

[Brandon Knope]

When each case only takes up one line, it may look nice and concise. But what happens in the common case when your case takes up more lines and you indent your braces?

> switch x {
> case 0 { print(0) }
> case 1 { print(1) }
> case 2 { print(2) }
> default { print("other”) }
> }

switch x {
case 0 { 
    print(0) 
}
case 1 { 
    print(1) 
}
case 2 { 
    print(2)
}
default { 
    print("other”) 
}
}

I think this looks much heavier and harder to read.  All the braces detract from the important stuff
