in reply to Scalar assignment with loop iterator considered bad?

For that particular piece of code I'd use 

$var = join ', ', @columns;

Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?

The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.

    Your code doesn't do the same thing. It leaves out the last comma.

      Fair enough 

      $var = join( ', ', @columns ) . ', ';

        Of course, we still have an extra comma-space if @columns is empty...

        Arg. Sorry, couldn't resist. :)
