<div>It's a good question, and I'd like to see more examples of what people=
 do, and maybe a best practice. Instead of die, my app throws named excepti=
ons (cf. Exception::Class), which are easy to catch, and you can provide ap=
propriate error msgs to the user based on what type of exception you caught=
.
</div>
<div>&nbsp;</div>
<div>Every one of my controller actions looks basically like this:</div>
<div>&nbsp;</div>
<div>sub foo : Local {</div>
<div>&nbsp;&nbsp; eval {</div>
<div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ... do all the foo stuff, and thr=
ow exceptions where necessary</div>
<div>};</div>
<div>if ($@) {</div>
<div>&nbsp;&nbsp; my $err =3D $@;</div>
<div>&nbsp;&nbsp; if ($err-&gt;isa(MyApp::Exception::File) {</div>
<div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; $msg =3D &quot;Could not open tha=
t file&quot;;</div>
<div>&nbsp;&nbsp; }</div>
<div>
<div>&nbsp;&nbsp; elsif ($err-&gt;isa(MyApp::Exception::Number) {</div>
<div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ...&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=
&nbsp;&nbsp;</div>
<div>&nbsp;&nbsp; }</div></div>
<div>&nbsp; ... etc.</div>
<div>}</div>
<div>&nbsp;</div>
<div>Of course there are other ways to return error values, and it's a judg=
ement call which way to choose -- but in places where you're inclined to ca=
ll &quot;die&quot;, this works very nicely.</div>
