The whole twitter thread is interesting with links such as: https://www.researchgate.net/publication/307088989_Some_Trouble_with_Transparency_An_Analysis_of_Student_Errors_with_Object-oriented_Python https://mail.python.org/pipermail/python-ideas/2016-October/042672.html https://github.com/ipython/ipython/pull/9073/files Also, the corresponding commit is: https://bitbucket.org/pypy/pypy/commits/e664458f25d07bbc8378161dcd8973df6a701b96 (includes nice tests)

``` >>> 3.5 ^ 2 Traceback (most recent call last): File "", line 1, in TypeError: unsupported operand type(s) for ^: 'float' and 'int' >>> 3.5 ** 2 12.25 ```

``` >>> raise NotImplemented Traceback (most recent call last): File "", line 1, in TypeError: exceptions must be old-style classes or derived from BaseException, not NotImplementedType ``` A fuzzy match...

`TypeError: unhashable instance` Maybe suggest how to make the instance hashable (on custom classes), maybe suggest hashable types (`frozenset`, `tuple`, etc).
