 * custom (decoupled) pools ==> N-buffering, shared components, multi-model, hibitsets, and so on
 * add examples (and credits) from @alanjfs :)
 * static reflection, hint: template<> meta_type_t<Type>: meta_descriptor<name, func..., props..., etc...> (see #342)
-* add meta support to registry (eg entity for each component and opaque get)
-* allow for custom stamp functions
 * observer: user defined filters (eg .replace<T, &function> or .group<T, U, &func>)
 * use underlying_type as entity type within pools and registry? it would make different registries work together flawlessy
 * can we write a bool conv func for entt::entity that silently compares it to null?
