    So many letters here... is it a comment by Mychaela? Oh, no, it's Neels!

    Just a few cents from me: if properly implemented, a metaclass allows you to pass variables in both ways:

    ```
    # like this
    class Foo(metaclass=MetaFoo, a=1, b=2):
        ''' ... '''
       
    # and like this
    # like this
    class Foo(metaclass=MetaFoo):
        a = 1
        b = 2
        
    # or both at the same time
    class Foo(metaclass=MetaFoo, a=1):
        b = 2
    ```

    This can be achieved as follows:

    ```
    class MetaFoo(abc.ABCMeta):
        def __new__(mcs, name, bases, namespace, **kwargs):
            x = super().__new__(mcs, name, bases, namespace)
            x.a = namespace.get('a', kwargs.get('a', None))
            x.b = namespace.get('b', kwargs.get('b', None))
            return x
    ```

    A good example is `ApduCommandMeta`.
