           Summary: typeof immutable fields order dependent
           Product: D
           Version: D2
          Hardware: All

When declaring an immutable field using typeof() on another immutable field,
the field in typeof() has to be declared above or the new one won't be
immutable.

Code:
```
typeof(a0)    b0 = 3;
immutable int a0 = 4;
pragma(msg, typeof(b0));

immutable int a1 = 4;
typeof(a1)    b1 = 3;
pragma(msg, typeof(b1));
```

Expected:
immutable(int)
immutable(int)

Actual:
int
immutable(int)
