Why do the commented out calls to goo fail?

Thanks

-------------------------------------
import std.stdio;
struct S {
}
void goo(const ref S s) {
   writeln(s);
}
struct T {
   S s;
   void foo(const ref T other) const {
     goo(s);
     // Error: function fdsaf.goo (ref const(S) s) is
     //        not callable using argument types (S)
     // goo(cast(S)s);
     // goo(cast()s);   // same error
     writeln(typeid(S), " ", typeid(s), " ",
             typeid(cast()s), " ", typeid(cast(S)s));

   }
}
void main() {
   T t;
   t.foo(t);
   const S s1;
   S s2;
   goo(s1);
   goo(s2);
   goo(cast(S) s2);
   // goo(cast(S) s1); Also fails

Compiles fine with git-head.

I did git clone: git clone

Then I built only dmd per instructions here 
http://xtzgzorex.wordpress.com/2011/07/31/d-building-dmd-and-phobos-on-linux/

dmd -v
DMD64 D Compiler v2.061

I assume that is all that is necessary. I ran this dmd on the 
code (with comments removed of course) and got the same error:

dmd  -g -w -property  /.../tmp/fdsaf.d
/.../tmp/fdsaf.d(11): Error: function fdsaf.goo (ref const(S) s) 
is not callable using argument types (S)
/.../tmp/fdsaf.d(12): Error: function fdsaf.goo (ref const(S) s) 
is not callable using argument types (S)
/.../tmp/fdsaf.d(26): Error: function fdsaf.goo (ref const(S) s) 
is not callable using argument types (S)

Any suggestions?

Thanks
Dan

Ah, okay. I just dumped it into a file and ran dmd before leaving 
the office.

This looks like a compiler bug to me. The struct should be 
implicitly convertable to const(S)
