This isn't harder than implementing __sizeof__ or pickling support, and NumPy classes already have implemented both. Maybe Yury forgot about METH_STATIC and METH_CLASS?<br>

</span>I just tested __class_getitem__ defined via METH_STATIC and it works.<br>
This means we don't need to add slots. Thanks for the hint, Serhiy!<br>

Ivan, this might be worth mentioning in the PEP or in the docs.</blockquote><div><br></div><div>I think it should be added to the PEP. Somehow I didn't think about C extensions, but now I see that it is important, also recently there appeared a lot of interest in better support of static typing for NumPy arrays and numeric stack.</div><div>I will make a PR a bit later.<br></div><div><br></div><div>--</div><div>Ivan</div><div><br></div><div><br></div></div></div></div>
