(1)[0] means 1[0], which is probably undefined, so it dies. That could be detected at compile time. (my $foo = 1)[0] means $foo[0], which would die at runtime, unless there's type inference going on. In any case, I don't see a List in ()[] without a list-creating expression in the (). > -Scott -- wolverian
