not appear at the very begin of an expression but all the rest is ok.

meaning those are correct

      if (( $1 == 4 )) { echo good } else { echo bad }

      if (( $1 == 4 )) {
          echo good
      } else {
          echo bad
      }

this is not

      if (( $1 == 4 )) {
          echo good
      }
      else {
          echo bad
      }

This is very helpful & clarifies. I 'd forgotten that shells are morestrict in their response to 'white space' than programming languages .

While playing golf I've noticed that the 'else' clause is particularlyintolerant it needs '} else {'
