I have no idea why eval drops this instead of converting to $@, but you can check $! after a block exit.
$ perl -e'eval{open my $fh, ">", "/dev/full"; print $fh "Foo\n";}; pri
+nt $!'
No space left on device
It would be wise to clear $! beforehand so you don't see leftovers.
use Fatal qw/open close/;
{
$! = undef;
open my $fh, '>', '/dev/full';
print $fh 'short text' or die $!;
}
die $! if $!;

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).
