This is brilliant, exactly what I was looking for. I did a profile recently on some API calls and found that 40-50% was being spent on serialization with marshmallow, which I'm looking to drop.

I'll be doing this stuff for myself, but would you be curious in having:

a) Support for lima: https://lima.readthedocs.io/en/latest/

b) more benchmark cases (serializing a larger list of objects)
