No great way to inherit from another Vlad #26

For example, if we have:

class YourFirstValidator(Vlad):
    source = LocalFile('vampires.csv')
    validators = {
        'Column A': [
            UniqueValidator()
        ],
        'Column B': [
            SetValidator(['Vampire', 'Not A Vampire'])
        ]
    }

And we wanted to create a new class that slightly modifies the existing Vlad, we'd have to do:

class YourSecondValidator(YourFirstValidator):
    validators = YourFirstValidator.validators
    validators['Column C'] = SetValidator(['Real', 'Not Real'])

(this one's for you, @dmcclory)
