The following code compiles with DMD 2.070, but not with 2.071:

         int unique_identifier_name;
         int tail;
     }

     Inner inner;
     alias inner this;

     auto works()
     {
         return unique_identifier_name;
     }

     auto fails()
     {
         return tail; // Line 22
         // The workaround:  return this.tail;
     }
}
```

The 2.071 error is:
tail.d(22): Error: template tail(Range)(Range range, size_t n) if
(isInputRange!Range && !isInfinite!Range && (hasLength!Range ||
isForwardRange!Range)) has no type

Is this because of the new import rules, or is it a bug?

Thanks,

I believe in the new import rules, all module members should override any imported ones, unless the import is renaming (which is equivalent to aliasing into your local namespace the symbol).

Now, the question here is, when does alias this kick in? I would say it should follow alias this before looking outside the module, so I say it's a bug.
