I use something like this:
package OpenOrDie;
use strict; use warnings;
use vars '@ISA @EXPORT $VERSION';
require Exporter;
$VERSION = '0.30';
@ISA = 'Exporter';
@EXPORT = 'Open';
sub Open {
my ($mode, $file) = @_;
open my $fh, $mode, $file
or die("Unable to open file '$file' using mode '$mode': $!")
return $fh;
}
Which I then use like:
use OpenOrDie;
my $FILE = Open('<',$filename);
This also means I can catch the error consistently:
eval {
my $FILE = Open('<',$filename);
}; if ($@) {
warn("Cannot parse configuration; $@");
$config{skip} = 1;
}

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).
