So you propose: if the variable exists in a wider scope, you ideal
python would not create it in an inner scope. How is this helping your
original case?

I remind you:

class ValueColumn(AbstractColumn):
    def __init__(self, name, header, domain_names):
        if type(domain_names) != tuple:
            raise ValueError('blub')
        for name in domain_names:
            if type(name) != str:
                raise ValueError('blub')
        self.domain_names = domain_names
        super(ValueColumn, self).__init__(name, header)

When "for name" is reached, "name" already exists and no local
variable would be created. How does this help you?
