          Issue ID: 23528
           Summary: moduleName/fullyQualifiedName no longer works in
                    -betterC
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: alphaglosined gmail.com

Regression in dmd 2.101.0.

Example:

```d
struct Foo {
}

import std.traits;
pragma(msg, fullyQualifiedName!Foo);
```

Also applies to moduleName.

Error message:
