(if (> x 2)
        (do-this when-true)
      (also-do-this when-true))

In some other language:

    x > 2 ? doThis(whenTrue) : alsoDoThisWhenTrue();

Same problem. Maybe even slightly worse. For example it could be:

    x > 2 ? doThis(whenTrue) ; alsoDoThisWhenTrue();

To spot the difference between a colon and the semicolon: tough.
