Subject: How to do group Exception classes?

Hi, I've some exception that I want to group into "AuthError" class so I can 
do a "raise" for the specific child exception or for the parent class. Is the 
following correct?

---------------------------
module Auth

	class GenericError < StandardError
	end

	class WrongPassword < GenericError
	end

	class ExpiredAccount < GenericError
	end

end
----------------------------


so now I can do:

----------------------------
begin
	raise Auth::WrongPassword
rescue Auth::GenericError => e
	puts "Exception class rescued: #{e.class}"
end

=> Exception class rescued: Auth::WrongPassword
----------------------------

This is: I didn't do a "rescue" for Auth::WrongPassword, but for 
Auth::GenericError.
But since Auth::WrongPassword is a child of Auth::GenericError then the rescue 
is executed and "e" is  Auth::WrongPassword.


Do you suggest a better way of doing it? Thanks a lot for any suggestion.
