Review Comment:
NIT: Maybe it would be good to add a comment (at least until we have 3.8)
that this is going to work because of `@cached_property` implementation which
is (as of 3.9) documented but it was an implementation detail in 3.8.
Compare:
https://docs.python.org/3.9/library/functools.html#functools.cached_property
with:
https://docs.python.org/3.8/library/functools.html#functools.cached_property
That was added in 3.9 only (but 3.8 worked this way as well).
```
Th cached_property decorator only runs on lookups and only when an attribute
of the same name doesn’t
exist. When it does run, the cached_property writes to the attribute with
the same name. Subsequent
attribute reads and writes take precedence over the cached_property method
and it works like a normal
attribute.
