hard disagree. Mistyped a name? with classes you get an error on compile time. Dictionaries? only on runtime.
plus, you won't need to remember every field because your editor can autocomplete it for you
There is more than one language out there
“Type safe dictionary” is just another way of saying “object”
No it's not. Dictionaries are accessed by key whereas objects are accessed by field (which is a high level way of representing an offset in memory). So one of those two is at least 10x faster than the other.
please show a language whose HashMap type does compile-time checking. I am actually interested.
