If it were that simple, why do you think it isn't currently mandated?
Here's one example: reference cycles. When do they get detected?
Taking a really simple situation:
class Foo:
def __init__(self):
self.self = self
print("Creating a Foo")
def __del__(self):
print("Disposing of a Foo")
foo = Foo()
foo = 1
When do you expect __del__ to be called? How do you implement this
efficiently and reliably?
