--- Comment #2 from Alisdair Meredith <alisdairm at me dot com> --- I am trying to use these extensively as ways to collect related static assertions in my test suite for <concepts> and <type_traits>. By using consteval rather then constexpr, I get notified if any code is unexpectedly deferred to runtime, and can fix my own bugs.
