i think we definitely have/should have a guideline that if we have an if statement and the one line that it applies to is on the next line, it must be in brackets.  that is:
```scala
if(something) doSomething
if(something) {
  doSomething
}
``` 
are both ok
but 
```scala
if
  doSomething
```
is never ok, because it would be super easy for me to come along and do
```scala
if
  doSomething
  doSomethingElse
```
and think that doSomethingElse is bounded by the if statement when its not

I think that we've always had that convention
