> A more general question: if an tvm_ffi.Object's constructor is not
defined, say its name is Foo, what would Foo() do?
Based on my understanding, I think
1. Object container class (FooObj : public Object): FooObj() calls the
compiler-generated default constructor, which invokes Object()'s constructor
and default-initializes member fields. However, I think this might not be the
prper way to create objects. Should we use `make_object<FooObj>()` instead?
2. ObjectRef handle class (Foo : public ObjectRef):
- If using `TVM_FFI_DEFINE_OBJECT_REF_METHODS_NULLABLE`: Foo() creates a
null/undefined reference
- If using `TVM_FFI_DEFINE_OBJECT_REF_METHODS_NOTNULLABLE`: Compilation
