No, what you're doing is fine and supported, but I generally arrange  
to throw exception objects (instead of strings).

These don't get in any way mangled by Catalyst, allowing you to  
fiddle with them in end to do things such as internationalizing them,  
or serializing them in API interfaces, and also means that I have  
less flow control to deal with in exceptional cases..

But throwing strings around is however a perfectly valid technique.
