I see I have to fix it myself then...

Here 'name' is the class name

Here 'name' is the the last key of classdict which is passed to type.__new__ 
instead of the actual class name.

[Fixed version]

class Type(type):
    def __new__(class_, classname, bases, classdict):
        newclassdict = {}
        for name, attr in classdict.items():
            if getattr(attr, "test", False):
                assert not name.startswith(PREFIX)
                name = PREFIX + name
            assert name not in newclassdict
            newclassdict[name] = attr
        return type.__new__(class_, classname, bases, newclassdict)
