It's not. Or rather, it's possible, but of limited utility.

Describe produces the reflection metadata in a form with which we can do something in today's C++. The C++23/26 reflection produces a constexpr vector<meta::info> which can be manipulated via C++20 consteval functions, but to actually do something useful with the result, you need injection, which is also part of the same 23/26 package.
