I really prefer that such simple enums are done as one liners instead of vertically. Possibly others don’t agree.

This can just be:

    ClassifiedControls(ClassifiedControls&&) = default;

But also, if you just omit all constructors you should get these without writing anything.

Idiomatic to just share a break.

In the context of a class named ClassifiedControls, seems this can just be called types().

Thanks for the review!

Makes sense! Changed to `enum class ModalContainerObservationPolicy : bool { Disabled, Prompt };`.

Good catch — removed these constructors.

Fixed!

That's true — renamed to just `types()`.
