Indeed, and it seems to depend on how name and vals are used:
... print(locals())
...
{'name': '__builtins__', 'val': <module 'builtins' (built-in)>, '__builtins__':
<module 'builtins' (built-in)>, '__package__': None, 'Context': <class
'__main__.Context'>, '__name__': '__main__', '__doc__': None}
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
RuntimeError: dictionary changed size during iteration
... pass
...
>>> locals()
{'name': '__doc__', 'val': None, '__builtins__': <module 'builtins'
(built-in)>, '__package__': None, 'Context': <class '__main__.Context'>,
'__name__': '__main__', '__doc__': None}
>>>
