[issue35570] 2to3 creates code using deprecated imp module

[Hanno Boeck]

New submission from Hanno Boeck <hanno at hboeck.de>:

2to3 (in python 3.6.6) will rewrite the reload function to use the imp module. However according to [1] "Deprecated since version 3.4: The imp package is pending deprecation in favor of importlib."
Also running the code with warnings enabled will show a deprecation warning.

Example, take this minimal script:

#!/usr/bin/python
import sys
reload(sys)

Running to 2to3 ends up with:
#!/usr/bin/python
import sys
import imp
imp.reload(sys)

$ PYTHONWARNINGS=d python3 foo.py
test.py:3: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses
  import imp
