Revamp object system, start using `gc` crate Wow, what a ride. I think everything should be working now. In short: * Objects use the `gc` crate, which as a `Gc` garbage-collected pointer type. I may choose to implement my own in contiguous memory in the future. We will see. * The type system is no longer global. This is a bit of a burden, because now, whenever you want to create a new object, you need to pass its type object into the `Obj::instantiate` method, as well as its `::create` static method. * This burden is somewhat alleviated by the `ObjFactory` trait, which helps create new objects as long as you have access to a `builtins` hashmap. So something that would normally look like this: fn init_builtins(builtins: &mut HashMap<String, ObjP>) { let print_builtin = upcast_obj(BuiltinFunctionInst::create( ObjP::clone(&builtins.get("BuiltinFunction").unwrap()), "print", print, 1 ); builtins.insert("print".to_string(), print_builtin) // other builtins inserted here... } now looks like this: fn init_builtins(builtins: &mut HashMap<String, ObjP>) { let print_builtin = builtins.create_builtin_function("print", print, 1); builtins.insert("print".to_string(), print_builtin); } (turns out, if all you need is a HashMap<String, ObjP>, you can implement ObjFactory for HashMap<String, ObjP> itself(!)) Overall, I'm happier with this design, and I think this is what is going to get merged. It's a little weird to be querying type names that are used in the language itself to get those type objects, but whatever works, I guess. Next up is vtables.
