The Parenthesis-Whitespace rule should not exist. It makes no sense, especially in closures.

It turns functions that look like this:

MyClass.executeClosure { (param) -> retVal in

}

to the following:

MyClass.executeClosure {(param) -> retVal in

}

Looks really ugly.

I'm disabling the rule, but I hope you consider removing it.
