[Issue 9147] New: Implicit conversion to struct with alias this does not work
http://d.puremagic.com/issues/show_bug.cgi?id=9147

          Summary: Implicit conversion to struct with alias this does not
                   work
          Product: D
          Version: D2
         Platform: All
       OS/Version: All
           Status: NEW
         Severity: critical
         Priority: P2

struct bbyte {
   byte b;
   alias b this;
}

void bar(bbyte b) {}

bbyte baz() {
   byte b;
   return b; // cannot implicitly convert expression (b) of type byte to bbyte
}

void main() {
   byte b;
   bar(b); // function bar (bbyte b) is not callable using argument types
(byte)
}

The above code fails on the marked lines as it's trying to convert the byte to
a bbyte. Ref discussion:

This is not a bug, it's working as intended.  D does not support implicit
construction like this.
