Regression was introduced in 1.061 by the fix to bug 4016, in expression.c,
DsymbolExp::semantic()

     //printf("Identifier '%s' is a variable, type '%s'\n", toChars(),
v->type->toChars());
     if (!type)
    {
+       if (!v->type && v->scope)
+        v->semantic(v->scope);
        type = v->type;
         if (!v->type)
         {    error("forward reference of %s %s", v->kind(), v->toChars());

The code doesn't fail on D2, because v->scope is not set on D2.
