Re^3: RFC: Idiom for named read-write arguments (aliases) instead of using $

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	[reply]

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.
