That section says that [[maybe_unused]] can be applied to a non-static data
member, which doesn't mean it can't be applied to a static data member.
And I'm arguing that since a static data member is a variable,
[dcl.attr.unused]p2 actually allows [[maybe_unused]] to be applied to a static
data member.
