digitalmars.D - Why won't this compile using DMD?

I'm stumped. Can anyone tell me why this won't compule using DMD 
(v2.060)? It compiles and runs just fine using GDC:

import std.stdio;
import std.concurrency;

shared class Data
{
public:
   this(int count)
   {
     m_count = count;
   }

   int count() const
   {
     return m_count;
   }

private:
   int m_count = void;
}

int main()
{
   Tid tid = spawn(&threadFunc, thisTid);
   while (true)
   {
     auto data = receiveOnly!(Data);
     writefln("Count is %s.", data.count);

     if (data.count == 0)
       break;
   }

   return 0;
}

void threadFunc(Tid owner)
{
   for (int count = 10; count >= 0; --count)
   {
     auto data = new Data(count);
     send(owner, data);
   }
}


The errors I get from DMD are:

test.d(27): Error: function test.Data.count () shared const is 
not callable using argument types ()
test.d(29): Error: function test.Data.count () shared const is 
not callable using argument types ()
/usr/include/dmd/phobos/std/concurrency.d(467): Error: static 
assert  "Aliases to mutable thread-local data not allowed."
test.d(41):        instantiated from here: send!(Data)

The problems all have to do with one thing - shared class Data does
not mean every instance of the class is shared, only that all member
functions are.

Hence,


      auto data = receiveOnly!(Data);



should be

auto data = receiveOnly!(shared Data);

and


      auto data = new Data(count);



should be

auto data = cast(shared)new Data(count);

shared then any instance of it would be as well.

      auto data =3D new Data(count);




 should be

 auto data =3D cast(shared)new Data(count);



 Or
 auto data =3D new shared(Data)(count);



I thought I'd tried that. Maybe it was

auto data =3D new shared Data(count);

Someone else may be better able to explain this but "most" D lex token
enclose until the end of the line unless de-marked with a pair of  ().
So I think 'new shared Data(count);' becomes 'new
shared(Data(count));'.
