CODE EXAMPLE FOR PYTHON

using decorators

    def __init__(self):
        self.classes = {}

        self.classes[c.__name__] = c

    # -- the decorator
    def held(self, c):
        self.add_class(c)

        # Decorators have to return the function/class passed (or a modified variant thereof), however I'd rather do this separately than retroactively change add_class, so.
        # "held" is more succint, anyway.
        return c 

    def __getitem__(self, n):
        return self.classes[n]

@food_types.held
class lemon:

print(food_types['bacon'].taste) # No manual add_class needed! :D
