C# also has exactly the same concept. "class"-types are put on the heap and get assigned by reference, while "struct"-types are assigned by copy. It always seemed weird to me. You need to know which data type you are working with when passing things around and can not adjust according to the application. For certain types from the standard library it makes sense, like datetimes you probably want always be copied. But when you work in a big team where everybody has their own style and special optimization corner case, it decays quickly.
