New submission from Quentin Peter <[email protected]>:
When both namespace arguments are given to exec, function definitions fail to
capture closure. See below:
```
Python 3.8.6 (default, Oct 8 2020, 14:06:32)
[Clang 12.0.0 (clang-1200.0.32.2)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> exec("a = 1\ndef f(): return a\nprint(f())")
1
>>> exec("a = 1\ndef f(): return a\nprint(f())", {})
1
>>> exec("a = 1\ndef f(): return a\nprint(f())", {}, {})
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 3, in <module>
File "<string>", line 2, in f
NameError: name 'a' is not defined
>>>
```
