Alias this member shadowed by imported function identifier?

[Johan Engelen via Digitalmars-d-learn]

The following code compiles with DMD 2.070, but not with 2.071:
```
module mod;

import std.range;

struct S
{
    struct Inner
    {
        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,
