The function literal_eval is not safe anymore as the constructor can be intercepted:

>>> import builtins
>>> def evil_code(*args):
...     print("Something evil")
...
>>> builtins.set = evil_code
>>> import ast
>>> ast.literSomething evil

KeyboardInterrupt
>>> ast.literal_eval("set()")
Something evil


I think we should either use {0}.__class__.

Also, the documentation now is wrong as the function does more than evaluate literals or container displays.
