PERTAIN_TOSolution

you can rely on `std::get` and the `std::tuple` machinery — if you want to access the nth argument. Tension: Using a variadic template should make it possible to have more readable code. Outcome: you could use some alias that retrieves the required index from a `std::tuple` defined in the template parameters.

PERTAIN_TORootCause

I get "ambiguous template instantiation" error — Suppose we have the following `struct` templates. Outcome: add an extra parameter and a type trait.

PERTAIN_TOProblem

I get "ambiguous template instantiation" error.

PERTAIN_TOSolution

You can add an extra parameter and a type trait to check whether second parameter is `Bar`.

PERTAIN_TORootCause

Outcome: introducing an indirection.

PERTAIN_TOSolution

I was able to solve the problem by introducing an indirection.

PERTAIN_TOProblem

static assertion failed due to requirement 'std::is_move_constructible_v' — in instantiation of template class 'MyVector' requested here. Tension: Is it because `std::is_move_constructible_v` is not a friend of `MyClass`?

PERTAIN_TOSolution

I'd recommend using `requires`-based checks instead of the traits in `MyVector`. — if you use `MyClass` with them. Tension: they won't be able to perform the actions that the traits say they can. Outcome: instead of the traits in `MyVector`.
