Yeah, the example confirms what I had guessed from your description.

And it´s *exactly* the point why I hesitated and thought the transparent [] delimiters could actually be a stupid idea. The outer [] delimiters conflict with the inner ones. But then I thought: Luckily there´s an opening and a closing square bracket, so nesting shouldn´t be a problem.
