[Catalyst] Using exceptions in Catalyst?

[Nate Wiger]

I'm wondering what people think the "best practices" are for handling 
exceptions in Catalyst. The project I'm working on has a number of 
modules by different programmers, and not all are written within 
Catalyst (ie, they are external modules).

Is it best to have these throw exceptions, then catch them in Catalyst 
and use $c->error? Is something like Error.pm suitable, or are there 
better alternatives? Or are there completely different approaches?
