 * built-in no-pagination storage - no_pagination page size as limits::max
 * any cdynamic to support const ownership construction
 * meta non-const allow_cast overloads: (const int &) to (int &) is not allowed, but (const int &) to (double &) is allowed (support only for convertibles)
-* review build process for testbed (i.e. tests first due to SDL)
 * paged vector as a standalone class
 * resource: shared_from_this?
 * archetype-like a-là EnTT support (see my own notes)
