+ * \brief Invokes the constructor of a particular object type and returns an
`ObjectRef`.
+ * \tparam T The object type to be constructed.
+ * \tparam Args The argument types.
+ * \param args The arguments to be passed to the constructor.
+ * \return The constructed object wrapped in an `ObjectRef`.
+ * \note This is usually used in FFI reflection boundary to register
`__init__` methods.
+ *
+ * Example
+ *
+ * \code
+ *
+ * class ExampleObject : public Object {
+ * public:
+ * int64_t v_i64;
+ * int32_t v_i32;
+ *
+ * ExampleObject(int64_t v_i64, int32_t v_i32) : v_i64(v_i64),
v_i32(v_i32) {}
+ * TVM_FFI_DECLARE_OBJECT_INFO("example.ExampleObject", ExampleObject,
Object);
+ * };
+ * refl::ObjectDef<ExampleObject>()
+ * .def_static("__init__", refl::InitOf<ExampleObject, int64_t, int32_t>);

Review Comment:
to align with pybind, let us do `refl::init<FunctionName>`
