The difference between a box with one apple in it and a single apple is critical.
In fact, I think that is the source of the most common type issue in real Python code:
You can't tell the difference (without type checking) between a sequence of strings and a string. Because, of course, a string IS a sequence of strings. In this case, there is no character type, i.e. no type to represent a single apple. (Kind of an infinite Russian doll of Apple boxes...)
Type hinting will help address the issue for strings, but it seems a very useful distinction for all types.
