* Raise ValueError for None in Expr lists to match CPython validator
CPython raises ValueError("None disallowed in expression list") when
compile() encounters None as an element in a Vec<Expr> position
(Set/List/Tuple.elts, BoolOp.values, Call.args, comprehension generators,
etc.). RustPython reached the catch-all TypeError("expected some sort of
expr, but got {}") branch instead, failing a dozen test_ast validator
tests.
Add an explicit is_none() check in Expr::ast_from_object before the
catch-all so None short-circuits with the CPython-compatible ValueError.
Option<Expr> positions (e.g. Dict.keys for **unpack) are unaffected
since node.rs Option<T>::ast_from_object handles None earlier.
Unmasks 12 skip / expectedFailure markers in
Lib/test/test_ast/test_ast.py:
- test_boolop, test_set, test_list, test_tuple
- test_call, test_delete, test_assign
- test_dict, test_dictcomp, test_generatorexp, test_listcomp, test_setcomp
Addresses part of the skip-test inventory in #7611.
The Stmt-level analog (body=[None] -> "None disallowed in statement list",
used by test_classdef) needs a sibling change in statement.rs; out of
scope here.
* Drop redundant .to_owned() on new_value_error argument
Matches the other new_value_error call sites in the file.

This directory contains all of the Python files that make up the standard
library for RustPython.
Most of these files are copied over from the CPython repository (the 3.7
branch), with slight modifications to allow them to work under RustPython. The
current goal is to complete the standard library with as few modifications as
possible. Current modifications are just temporary workarounds for bugs/missing
feature within the RustPython implementation.
The first big module we are targeting is unittest, so we can leverage the
CPython test suite.
