 * basic_any descriptor can go into the vtable, vtable can be used the same as descriptor (for fast return)
 * get rid of resolve function pointer in meta_any, use vtable for the one time lookup
 * introduce compile-time flag to skip dll-only checks in basic_any
+* auto policy for return types in meta (i.e. it picks as_is or as_(c)ref automatically as needed)
