Review comment:
Dictionaries are represented by a hash table and adding or removing
items while iterating over it will alter the iteration order. This will cause a
RuntimeError.
If you need to add items to the dictionary during iteration, it is
recommended to iterate over a shallow `copy` of the dictionary.
