 * refine the storage fallback mechanism for views (ie alloc?)
 * don't pass reactive storage by default to callback
 * runtime types support for meta for types that aren't backed by C++ types
-* dtor, traits and custom should be part of meta descriptor maybe (?)
+* dtor, traits and custom should be part of meta descriptor (update meta_factory tests then)
