I get an warning "Lambda arguments should be moved outside of parenthesis"

I am getting a warning from IntelliJ with this line of code 

val cards: Array<Card> = Array(52, { Card(it % 13, getSuit(it)) })

which is the same code from the lesson; however when I removed the parenthesis at the end 

  val cards: Array<Card> = Array(52) { Card(it % 13, getSuit(it)) }

The warning went away, just curious as to why the warning is popping up or why Ben used the parenthesis in his example.

Thanks!
