So dct is something like a template rather than the __dict__ of the
actual class?
I'd assume that changing the content of a dict would be possible even
after it has been assigned to some object (here, a class).

Are wrap and get_directives somehow built-in? I couldn't find
references to them.
I've noticed, too, that using __new__ I can manipulate the dictionary
resulting in the behavior I intented.
I'd rather like to know: Why does it work in __new__ but not in
__init__?
And, stimulated by your response

There is a confusion of self and cls

Hello,
I've been experimenting with metaclasses a bit (even though I am quite
a newbie to python) and stumpled over the following problem in my code:
class Meta(type):
def __init__(cls, name, bases, dct):
for attr, value in dct.items():
if callable(value):
dct[attr] = wrapper(
