[New-bugs-announce] [issue37409] relative import_from without parent

[Ben Lewis]

New submission from Ben Lewis <benjamin.r.lewis at gmail.com>:

>>> from curses import ascii
>>> from . import ascii

The second line should raise an ImportError but instead succeeds (tested cpython 3.6.7, 3.7.0 and 3.7.3, and from interactive interpreter and scripts). Specifically, builtins.__import__ does not reproduce the behaviour of importlib._bootstrap.__import__; maybe ceval.c:import_from is neglecting to check that there are parent packages when attempting a relative import?
