[docs] [issue22525] ast.literal_eval() doesn't do what the documentation says

[Behdad Esfahbod]

Behdad Esfahbod added the comment:

I think it should be made much more clear that this is not a blanket "safe eval() replacement".

Re complex literals, note that Python 2.7.x only implemented the binary plus operator if the second argument was complex.  This seems to have been relaxed in Python 3.

Regarding DoS attack with a safe eval(), I understand the concern, but that's still a huge improvement over security risks of eval().
