It's closer now indeed. It's not quite identical yet, as in one case we
have boolean, the other an uint counter. (There's a third case for class
runtime stats where it would be an atomic_t.) So not quite hitting the
rule of 3 for adequate generalisation, though maybe with some magic
macro constructors...
