The idea that I get from dogpile, is that in each module (getter.py, or
setter.py) there is a dictionary where the values are stored in the backend.
Hence, getter.py has its dictionary and setter.py has its dictionary also. In
the end, there is not a single dictionary where all the values should be put.
And I want a single dictionary.
