in thread Useless use of string in return statement

$a and $b should not be understood as stand-ins for "anything"

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.

        I chose my wording "should not be understood" carefully: it's a clarification for any reader for whom the distinction between $a || $b and @a || @b may be unclear. And maybe you missed the smiley at the end of my post above.

        So you were jousting at stars [concern-trolling] that never felt a wound.
