used-before-assignment not flagged for import while triggering UnboundLocalError

[chaen]

Steps to reproduce

importExample.py

# pylint: disable=missing-docstring,invalid-name
import time

def test():
    print(time.time())
    import time
    print(time.time())

test()

variableExample.py

# pylint: disable=missing-docstring,invalid-name
A = 1

def test():
    print(A)
    A = 2
    print(A)

test()

Current behavior

The execution of these two scripts lead to a similar outcome:

$ python importExample.py 
Traceback (most recent call last):
  File "importExample.py", line 9, in <module>
    test()
  File "importExample.py", line 5, in test
    print(time.time())
UnboundLocalError: local variable 'time' referenced before assignment

$ python variableExample.py 
Traceback (most recent call last):
  File "variableExample.py", line 9, in <module>
    test()
  File "variableExample.py", line 5, in test
    print(A)
UnboundLocalError: local variable 'A' referenced before assignment

pylint detects the problem correctly for the variable, but not for the import

$ pylint variableExample.py 
************* Module variableExample
variableExample.py:6:4: W0621: Redefining name 'A' from outer scope (line 2) (redefined-outer-name)
variableExample.py:5:10: E0601: Using variable 'A' before assignment (used-before-assignment)

-----------------------------------
Your code has been rated at 0.00/10

$ pylint importExample.py 
************* Module importExample
importExample.py:6:4: W0621: Redefining name 'time' from outer scope (line 2) (redefined-outer-name)
importExample.py:6:4: W0404: Reimport 'time' (imported line 2) (reimported)
importExample.py:6:4: C0415: Import outside toplevel (time) (import-outside-toplevel)

------------------------------------------------------------------
Your code has been rated at 3.33/10 (previous run: 1.67/10, +1.67)

Expected behavior

I'd expect to see E0601 raised in the case of the import as well.
