I don't think so. It depends what your code actually is of course, if you do silly things like throw 'eval' around then there could be holes everywhere..

Throwable(3pm)						User Contributed Perl Documentation					    Throwable(3pm)

NAME
Throwable - a role for classes that can be thrown VERSION
version 0.102080 SYNOPSIS
package Redirect; use Moose; with 'Throwable'; has url => (is => 'ro'); ...then later... Redirect->throw({ url => $url }); DESCRIPTION
Throwable is a role for classes that are meant to be thrown as exceptions to standard program flow. It is very simple and does only two things: saves any previous value for $@ and calls "die $self". ATTRIBUTES
previous_exception This attribute is created automatically, and stores the value of $@ when the Throwable object is created. METHODS
throw Something::Throwable->throw({ attr => $value }); This method will call new, passing all arguments along to new, and will then use the created object as the only argument to "die". If called on an object that does Throwable, the object will be rethrown. AUTHORS
