Append type hinting to the class

[samwaseda]

Following this discussion I finally realized what I had in mind, even though I have to admit it might not work exactly in the way I wish it would.

For this class:

from dataclasses import dataclass
from typing import Annotated

@dataclass
class Pizza:
    price: Annotated[float, "money"]
    size: Annotated[float, "dimension"]

    @dataclass
    class Topping:
        sauce: Annotated[str, "matter"]

I get the following behaviour:

from uniton.converter.append_types

append_types(Pizza)

print(Pizza)
print(Pizza.Topping)
print(Pizza.size)
print(Pizza.price)
print(Pizza.Topping.sauce)

Output:

<class '__main__.Pizza'>
<class '__main__.Pizza.Topping'>
typing.Annotated[float, 'dimension']
typing.Annotated[float, 'money']
typing.Annotated[str, 'matter']

The only one problem is that the default value is lost when there is one and it's accessed without instantiating the class, i.e.

@dataclass
class Pizza:
    size: Annotated[float, "dimension"] = 10

print(Pizza.size)
append_types(Pizza)
print(Pizza.size)

Output:

10
typing.Annotated[float, 'dimension']

But it doesn't really interfere with any functionality if it's instantiated. This being said, I would have loved to do it without overwriting the class, but I couldn't find any viable solution other than this one.
