Throwable - a role for classes that can be thrown
version 0.200012
package Redirect; use Moose; with 'Throwable'; has url => (is => 'ro');
...then later...
Redirect->throw({ url => $url });
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.
$@
die $self
Throwable is implemented with Moo, so you can stick to Moo or use Moose as you prefer.
This attribute is created automatically, and stores the value of $@ when the Throwable object is created. This is done on a best effort basis. $@ is subject to lots of spooky action-at-a-distance. For now, there are clearly ways that the previous exception could be lost.
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.
die
If called on an object that does Throwable, the object will be rethrown.
