AttributeError: 'CPUDispatcher' object has no attribute '__globals__' with numba.njit decorated function

[gatoniel]

Describe the bug
Sorry, for opening a new issue, but the old one was closed due to my late reply and I do not know whether you still get notifications for closed issues. So this is a continuation of: #277 Maybe you can reopen the old issue and close this one or we just continue here.

To Reproduce
With version 3.0.0b2 or the latest master branch run

from typing import TypeVar

import numpy as np
import numpy.typing as npt
from numba import njit
from typeguard import typechecked

T = TypeVar("T", bound=np.generic)


@typechecked
@njit
def numba_sum(
    array: npt.NDArray[T],
) -> T:
    return np.sum(array)

x = np.arange(4)
s = numba_sum.py_func(x)
s = numba_sum(x)

It gives me the following error message:

Traceback (most recent call last):
  File "/home/niklas/drescherlab/merge-stardist-masks/test.py", line 21, in <module>
    s = numba_sum(x)
  File "/home/niklas/.cache/pypoetry/virtualenvs/merge-stardist-masks-Mk5qjuGF-py3.9/lib/python3.9/site-packages/typeguard/__init__.py", line 286, in wrapper
    memo = CallMemo(python_func, _localns, args=args, kwargs=kwargs)
  File "/home/niklas/.cache/pypoetry/virtualenvs/merge-stardist-masks-Mk5qjuGF-py3.9/lib/python3.9/site-packages/typeguard/_memo.py", line 54, in __init__
    super().__init__(func.__globals__, frame_locals, config)
AttributeError: 'CPUDispatcher' object has no attribute '__globals__'

The problem is not with the .py_func but with the real njitted function.

Expected behavior
I expect the call to the njit decorated function to succeed.

Additional context
Copy of #277
