@m-burst This looks great; thanks a lot! Can you also add a test to make sure that the hash is in fact the same for identical data types? It's just nice to have a test both for the positive case and for the negative case. |
The added implementation XORs the `tuple.__hash__` of the data object with the hash of the class. This should help to avoid collisions between instances of different data types with identical members. Also added a test which ensures that: * hash of a data type instance can be computed; * hashes of instances of different data types with same data differ; * hash of a data type instance differs from hash of a plain tuple. Fixes #446.
