Looking again, I see you are right. Whilst related, they are not the same usage.

By way of penance:

sub swap{ our($a,$b); local( *a, *b ) = \( @_ ); ($a, $b ) = ( $b, $a ) } my( $x, $y ) = ( 1, 'fred' ); swap( $x, $y ); print "$x, $y";; fred, 1 print swap( 1, 'fred' );; fred 1

    good point, since $a and $b are magical globals you can even avoid the our-decalaration (in this case)

    Cheers Rolf

      Didn't think of that, but I have to wonder if $a & $b are really that much better than $_[0] & $_[1] ?

      Okay for swap(), I guess.
