Unwinding C++20 concept std::same_as all the way up the chain to std::integral_constant.
A compilation of "possible implementations" from cppreference. Hope seeing it all together at once helps appreciate how things work behind the scenes.
PS: read the code bottom to top; usable with no includes

If a user-declared constructor delegates to another constructor, it can help to delegate directly to the final constructor in the delegation chain, instead of delegating to a constructor which then delegates to another constructor, and so on. Direct delegation slightly increases maintenance effort, but *generally speaking*, it can improve speed and code size.
E.g., S1's default constructor involve

Like C, C++ allows declaring struct variables with struct types. The syntax seems odd (esp. in C-like code where it is common for the struct type and var to have the same name), but it makes sense if we see it alongside a var declaration for a primitive type (1).
But this syntax also permits odd qualifiers seemingly on types, but the quals really apply to the var not the type (2).
