Objects are not a complete implementation and lack features of classes (no interfaces mainly and constructing requires the new keyword). The syntax I propose lets you allocate classes on the stack on a per-request basis which means you can use the class on the heap when you need to pass it around, or on the stack when you know the life cycle of the class during compile time.
Isn’t that a better option then using Objects and getting stuck with their syntax?
