PEP 563 – Postponed Evaluation of Annotations

Use this https://peps.python.org/pep-0563/

By importing
`from __future__ import annotations`

To allow self-references instead of having to write in quotes, e.g. -> ‘AbstractDataset’.
Do this for all classes that have self-references.

(113866548)

The issue names no files or tests; start by locating Python classes that use quoted self-references and read PEP 563. Apply the requested future import consistently for those classes, then confirm all affected modules still load and self-references no longer need quotes.
