Review comment:
``{**dict1, **dict2}`` only merges the first dictionary. This function
also merges nested dictionaries.
```
>>> dict_a = {'A': {'B': {'C': 'D'}}}
>>> dict_b = {'A': {'B': {'E': 'F'}}}
>>> {**dict_a, **dict_b}
{'A': {'B': {'E': 'F'}}}
>>> merge_dicts(dict_a, dict_b)
{'A': {'B': {'C': 'D', 'E': 'F'}}}
```
