I think a metaclass [well, "pseudo-metaclass", to use a term I made up for a metaclass that is not a subclass of type and/or does not return an instance of type] would be better in this case because the resulting object should not be a type.

but a class decorator can return, well, anything. See the example I posted having it create a module object.

I really don't know that that's a good idea, but yeah, if what you want is a essentially a namespace, then you really don't want a type. Maybe just an instance of object would work though.

The reason I wanted different syntax was because I wanted to change how the functions inside are compiled [to allow nonlocal accesses to refer to the namespace's scope], though I think making them globals and a custom dict subclass [possibly ChainMap, haven't checked if it does everything I want] for globals makes this workable as a metaclass or decorator - either one can take all of the functions and replace them with a new function with different globals and the original function's code object.
