The "@compile-error" comment is an old not-great way of defining static error tests. Also fix a test to use a mixin declaration instead of a class for declaring a mixin. This was broken by class modifiers but the breakage was masked by @compile-error treating a test as passing if any compile error, even an unrelated one, is reported.
