Missing import ForwardRef

[TJNK]

Breaking change on the import of ForwardRef. New in python 3.7.4

File "/usr/local/lib/python3.6/site-packages/vfab2_library/suts/sut_config.py", line 17, in
import punq
File "/usr/local/lib/python3.6/site-packages/punq/init.py", line 30, in
from ._compat import ensure_forward_ref
File "/usr/local/lib/python3.6/site-packages/punq/_compat.py", line 2, in
from typing import ForwardRef
