Binary "err" is equivalent to C<//>--it's just like binary "or", except it tests its left argument's definedness instead of its truth. There are two ways to remember "err": either because many functions return C<undef> on an B<err>or, -or as a sort of correction: C<$a=($b err 'default')> +or as a sort of correction: C<$a=($b err 'default')>. This keyword +is only available when the 'err' feature is enabled: see L<feature> +for more information. Binary "xor" returns the exclusive-OR of the two surrounding expressions. It cannot short circuit, of course. |
