I think what Steven is saying is that you're distorting the concept of
a struct beyond recognition. What you really want/need is just some
kind of namespace inside the outer scope.
Note that D almost has what you want already if you do it through a
template mixin:

The
only thing missing is opGet or an equivalent, and probably a more
straightforward syntax. And perhaps someone should check whether the
functions can be made virtual too (another requirement that doesn't
really belong in a struct).
