This is an interesting project, thanks for sharing. It chimes with some stuff I’ve been working on recently.

I can see an immediate use for the mappers in my work.
I’ve been trying to make a practical implementation of ports and adapters in Django. I want to keep the helpful stuff that’s driven from models - model forms, rest serialisers, factory boy, hypothesis integration - but separate the domain objects from the persistence layer.

Is this related to your goals for this project?
Are there other helpful bits in there that I haven’t caught on to yet?

Thanks,
Ronan
