Re^2: Custom error messages and moose

There is pretty verbose:

+b/perl5/Evolvethinking/Unicorn.pm line 67, <FH> line 1.

        Mouse::Util::throw_error('Mouse::Meta::Attribute=HASH(0x20342d

+Evolvethinking/Unicorn.pm line 78

Yes, I can put a die or warn in the sub but, I'm wondering if there is a more Moose like way.
