[issue19268] Local variable created with reflection cannot be referenced with identifier

[Ivan Pozdeev]

New submission from Ivan Pozdeev:

It appears that the interpreter assigns an identifier to local or global scope at compilation time rather than searching locals, then globals (i.e. vars()) at the time of execution.

An example:

>>> def test():
...   vars()['a']=1
...   print(a)
...
>>> test()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 3, in test
NameError: global name 'a' is not defined
>>>
