I think that there should also be [limited] containers of limited types.
For this we need a construction model, which would allow user-defined
in-place constructors. After all Ada has always had arrays of limited
components. We have to extend this model onto user-defined containers.
I think that this would require separation of assignment from copy
constructor, as C++ does. Though the default must be that assignment is
generated from destructor and copy constructor.
