Elegant typehints cannot resolve forward-references

[ded8393]

Fails to resolve forward-references.

from dataclasses import dataclass
from typing import TypeVar, TYPE_CHECKING, Generic

@dataclass
class A: 
   b: 'B'  # NameError: 'B' is not defined

@dataclass
class B:
    a: A

Does not resolve even under conditions where the following are added to the top (forward-references should generally resolve via quotations, however PEP563 gives these suggestions

T = TypeVar('T')
if typing.TYPE_CHECKING:
    B = Generic[T]

from future import __annotations__

sphinx-autodoc-typehints uses parameter set_type_checking_flag in conf.py. Setting this does not affect elegant_typehints.

Can you give me a stack trace please? use a codeblock with the pytb “language”:

```pytb
...
```
