in thread Useless use of string in return statement

Not to mention that return $a ? $a : $b; can always* be written as return $a || $b;

Nitpick: $a and $b should not be understood as stand-ins for "anything", since @a || @b is not the same as @a ? @a : @b, since the former imposes scalar context on @a (and not on @b).

    True. I very consciously chose the scalars $a and $b. In fact, I had originally started to write return A ? A : B; but realized that that would not be sufficient, nor would it be necessary for the point (i.e. the OP's problem).

      True, but if you're going to be nitpicky and mention tied variables, then better go all the way ;-)

        If we're going to get that nick-picky, then I'll point out that $a and $b cannot be stand-ins for "anything" ... since they are scalars. So you were jousting at stars that never felt a wound.
