Pidanticis uses inheritance to give you this functionality. With seera, youyou have your pure python classes without any they don't need to inherit from anything. And i think that brings a lot of advantages in structuring soft ware. I also really love sater, because it has kind of a similar so you can serealize and deserealize data classes and errors. H t p x is has very similar interface, but gives you both a sink and and sink operations. It's deftly n one of my gotos as well.
