Update: I think this does what I want to do. The key is that config obj stores errors as Exceptions which can then be checked against those that subclass ValidateError. Then you just have to do one check per subclass rather than one check per parameter value.
It might be nicer if validate just threw an exception if validation failed but maybe you would lose other functionality.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
