My understanding of the original question is: what motivated you targeting C++20 instead of e.g. C++17

[_samt_]

My bad ! There wasn't a strong reason to target C++20 specifically. I simply choose the latest standard available at the time as started experiments.

In practice, the code generator doesn't rely heavily on C++20-only features, so targeting C++17 would likely be possible with some adjustments.
