Metafunctions and Daveed Vandevoorde's CPPCON video "Gazing Beyond Reflection for C++26"

[patrickdown]

I watched Daveed Vandevoorde's CPPCON video "Gazing Beyond Reflection for C++26." The two parts of the presentation I found most interesting were the token streams as compile time types and how custom attributes could be used to control code generation.

I know these proposals are not finalized but I was wondering how this would fit with cpp2's metafunctions.
