The above are great solutions, but there is one more.
You may have seen modules that have something like $Foo::errstr or the likes. Setting up something like that isn't too hard:
package Foo::Bar;
our $error = "";
sub new {
my( $class, @args ) = @_;
my $self = bless( \@args, $class );
unless( $self->method_that_might_fail() ) {
$Foo::Bar::error = "O noes";
return undef;
}
return $self;
}
Of course, you will have to change that to fit your style, and it is probably a good idea to push the error setting to a separate subroutine.

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).
