The workaround is just plain butt ugly and should be a sameful thing to
use.


 class SomeClass
 {
      version( D_Version2 )
      {
          mixin(`
           invariant void someMethod()
           {
           }
          `);
      } else {
          void someMethod()
          {
          }
      }
 }

 void main(){}
