The general idea is to have the metaclass create a mapping object which is used as the 'locals' dictionary for the suite following the class statement. There would be some special-named function of the metaclass, such as 'metadict', which would construct a new mapping object. I haven't seen many alternative proposals to this.

There's mine, where you simply create mcls(name, bases, {}) and then map locals operations to get/set/delattr operations on the class. This would presumably be done using a simple mapping proxy, but it would be a built-in type rather than the user having to implement their own mapping type.
