I have a working solution, this is a more general question.
I just finished a few hours on the meal maker exercise.
I ended up watching the walk through video and realised, THE SETTERS ARE NOT BEING USED in the official solution. Neither is the global courses getter.
I was struggling because I was trying to use the setters, and I still find no way of making it work by actually using the setters they ask to define in step 4.
Are they just dead code? Am I missing something??
