A fixed implementation is provided in
https://github.com/django/django/pull/3546
The initial implementation was provided by vanschelven, accepted and
commited as part of https://github.com/django/django/pull/3525. It however
broke in Python 3 due to how `__eq__` and `__hash__` behave.
I opted not to provide a default implementation of `deconstruct` method to
avoid arguments moving between `args` and `kwargs` depending on invocation
(like the deconstruction of model fields it always produces the canonical
form).
