Typesafe getter and setter

[jruebsam]

Currently setting the attributes of a derived class is not typesafe e.g.

@dataclass
 class Position(TypedJsonMixin):
    x : int 
    y : int 

p = Position(3, 3)
p.x = 1.2

is still possible. Does it make sense to overwrite the setatt method of the class
currently im doing this manually like this :

def __settattr__(self, name, value):
    if isinstance(value, type(getattr(self, name))):
        super().__setattr__(self, name, value)
    else:
        print(f'Type is not matching with that of {name} which is {type(getattr(self, name))}')

im not sure if this has some drawbacks at some point
maybe it would be an option
