I am trying to define a model Toto within another model Example1. I know this is not Best Practices, but Toto is purely meant for this specific model Example1 and I don’t want to see it in my package view.

Basically, I would like to end up with something like:

model Example1
    Toto toto;
    [...]
    model Toto
        [...]
    end Toto
end Example1

Is it somehow possible?
