  • Aggreget

    Use your structures like tuples. Similar to MagicGet but using C++ 20 concepts.

    • I made something similar a while ago : https://github.com/Baduit/Aggreget

  • pfr

    std::tuple like methods for user defined types without any macro or boilerplate code

    • It is an 'interesting' meta-programming problem though (wasted many weeks on it myself, fixed a small gcc bug - a 'uniform init' edge case and filed an issue with magic_get Reflecting array members of aggregate structs).
