New submission from ProgVal:
Since commit cb41b2766de646435743b6af7dd152751b54e73f (Python 3.7a0), string
literals are not parsed the same way.
ast.parse("'test'").body used to be a list with one item containing 'test'; but
now it is an empty list:
Python 3.5.2+ (default, Dec 13 2016, 14:16:35)

>>> import ast
>>> print(ast.parse("'test'"))
<_ast.Module object at 0x7fa37ae4c630>
>>> print(ast.parse("'test'").body)
[<_ast.Expr object at 0x7fa37ae4c630>]
>>> print(ast.parse("'test'").docstring)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'Module' object has no attribute 'docstring'
