subtype with stringify

[John Macdonald]

Is it possible to define a subtype that will provide a stringify method?

I see MooseX::Exception::Base::Stringify that can be provided as a trait for an attribute, but that gets onerous (and error-prone) when *every* time you declare an attribute that has "... isa => MyType ..." you want to also have "... traits => [qw{MooseX::Exception::Stringify}] ..." applied. It would be much more convenient to have the subtype provide the stringify capability.  I'm visualizing something like either a parameter to the subtype declaration to specify stringify (or other overloads, perhaps); or alternately a separate mechanism (like the way coerce is done) outside the subtype declaration that modifies it to have the overloaded stringify.
