Skipping the header in a for loop (implied with a statement modifier) is quite flexible as you can skip one, two or many lines with equal facility. It also has the advantage that the scalar receiving the readline only exists within the loop.
my $discard = <$fh> for 1 .. 1;
# $discard no longer in scope here.
I hope this is of interest.
Update: Fixed typo.
Update 2: ikegami has pointed out that this code is invalid and explained why so don't do this.

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).
