// Ensure that your macro reports a reasonable error message when the caller
// mistypes the inert attribute in various ways. This is a compile_fail test.
//
// The preferred way to report an error from a procedural macro is by including
// an invocation of the standard library's compile_error macro in the code
// emitted by the procedural macro.
