my method is similar, but different...
## let's say bar is a method in foo
sub bar
{
my( $self, @args )= @_;
eval { $self->method( @args ) };
$@ and $self->raise_error( @_ ) and return undef;
}
## called like:
my $foo= foo->new();
my $result= $foo->bar( @args )
or warn $foo->Error();
the method sets an error and returns undef, allowing the caller to deal with the error as it sees fit. of course, you might want to handle a method that can return 0 by using defined

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).
