* Implement attrs.validators.or_ validator
* Add tests/test_validators.py::TestOr test cases
* Add test for _OrValidator.__repr__ method
* Add description of attrs.validators.or_ to docs/api.rst
* Add changelog entry
* Swap double quotes for single because doctests don't like it
* Rename changelog fragment pointing to incorrect number
* Silence ruff linter warnings
Although good warning in general, in this particular code, they
do not fit here.
* BLE001 Do not catch blind exception: `Exception`
`validators` usually raise `ValueError` upon their violation.
However, it's not the only `Exception` they can raise - cf.
`attrs.validators.not_` - therefore, it is desirable to catch
them all!
* PERF203 `try`-`except` within a loop incurs performance overhead
Fair point, but the loop is written in a way to short-circuit,
ie. it will finish when a first validator is satisfied.
* S112 `try`-`except`-`continue` detected, consider logging the exception
Not applicable here, we care only if **all** validators raise
an exception, which is already accomodated for after the `for`
loop.
* Apply suggestions from code review

`attr.fields_dict` was a link back to itself. The intention, like all the other nearby aliases, was to refer back to the version in `attrs` for the full story.
* Add support for cached_properties to slotted attrs classes.
* Remove locking from implementation
* Add test for multiple cached properties and fix bug
* Add changelog file
* Document slotted cached properties
* Add cached_property hypothesis check.
* Only run cached_property imports on python 3.8+
* Use cached _obj_setattr instead of `object.__setattr__`
* Correctly resolve mro for __getattr__ in cached properties
* Use _get_annotations rather than branching on class dict entry
* Optimise __getattr__ code by front loading branching, and injecting locasl variables
* Remove unnecessary `__attrs_original_getattr__` from class dictionary.

* Pass args from `__init__` to `__attrs_pre_init__` if requested
Detect if `__attrs_pre_init__` has arguments besides `self`
using `inspect.signature`. If so, pass `__attrs_pre_init__`
the same arguments that `__init__` (or `__attrs_init__`)
expects.
* Add changelog entry for `__attrs_pre_init__` args changes
* Don't use monkeypatch in new code
* Clarify docs
* Missed one monkeypatching
