in thread while(<>) { ... } considered harmful

map { require Net::DNS } 1;
I believe that's a minimal demonstration of a bug, rather than "real" code.
On the subject of while(<>) vs. while(my $line = <>), I tend to prefer the former:
- If I don't have to do much processing for each line, it's usually much nicer to work on $_, as Juerd points out.
- If I do have a lot of work to do, it's usually in a subroutine call, where this sort of thing isn't an issue (since the scope has changed).
I haven't really thought about it, but if a loop's so complex that you have to assign to an explicit iterator variable just to figure out what's going on (as opposed to a loop where defaulting to $_ would be inappropriate for other reasons), it's probably an indication that the loop needs simplifying.
