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.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
