map { require Net::DNS } 1;
Is that a map in void context? Nasty and evil.
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.
