I had a bug where I was relying on methods being equal to each other when using `is`. It turns out that's not the case:

```
>>> class What:
...     def meth(self):
...         pass

>>> What.meth is What.meth
True
>>> inst = What()
>>> inst.meth is inst.meth
False

```

Why is that the case? It works for regular functions:

```
>>> def func(): pass
>>> func is func
True

```
