New issue 2253: Unbound method access creates fresh object each time
https://bitbucket.org/pypy/pypy/issues/2253/unbound-method-access-creates-fresh-object

David MacIver:

The following code passes on CPython 2.7.10 and fails on pypy-4.0.1:

```python
assert object.__repr__ is object.__repr__
```

The two unbound methods report as == but not identical on pypy.

I discovered this because the check that IPython pretty printing uses to test whether a type needs a custom pretty printer is whether type(c).__repr__ is object.__repr__. This works on CPython but fails on pypy.
