That's not all that different from Python, where object() returns a
fresh instance at each invocation. However:
>>> object().x = 3
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'object' object has no attribute 'x'
Why are object instances immutable in Python?
