![]() # Objective * The `SystemParam` derive internally uses tuples, which means it is constrained by the 16-field limit on `all_tuples`. * The error message if you exceed this limit is abysmal. * Supercedes #5965 -- this does the same thing, but is simpler. ## Solution If any tuples have more than 16 fields, they are folded into tuples of tuples until they are under the 16-field limit. |
