I am not sure that this is a bug. But it might be.
Please, feel free to close if this is expected.

This also happens:

>>> import inspect
>>> def func():
...     frame = inspect.currentframe()
...     print(frame.f_globals)
...     
>>> func()
{'__package__': '_pyrepl', ...}

I'm not fully sure this qualifies as a bug. Unsetting this can be quite painful because it can mess up with using PyREPL as a module which we use quite often to check for coverage or profile.

@ambv what do you think?
