Would it make sense to have a 'simpleobject'? Which basically implements 
a NamedTuple constructor but nothing more?

class Foo(simpleobject):
     attribute1: User
     attribute2: Blog
     attribute3: list

And if you need more __dunder__ magic, have it provided by some mixins?

class Foo(dictlike, tuplelike, simpleobject):
     attribute1: User
     attribute2: Blog
     attribute3: list

      def __my_dunder__(self):

I don't know exactly if some of those dictlike, tuplelike mixins are 
already available in the stdlib under a different name, but at least to 
me this looks like plug'n'play __dunder__ magic.
