I've implemented this, but I had to change the last [] to ().
Having [] both for nested databases and parameters works fine in
Python but doing it in C++ would mess up the inheritance completely.
I think it's doable but it would complicate the implementation.
So the above example would be
my_params.add(my_other_params);
my_params["another params"]("foo") = 1.0;
So the pattern is
parameters[][][][]()
or just
parameters()
