Thanks, Ali.
I just tried a few things, and apparently, you don't need to go
to a different type

Interesting. If you de-reference the pointer and assign it back,
do you get back the keep-alive? Like, in the receiving thread:
void threadFunc()
{
It looks like passing a pointer to an immutable(Message) works
as well:
Oh, yes, pointer. Ha! I didn't even think of that. Thanks.
I'm not familiar with how garbage collection works in D. If the
initial reference goes out of scope, and you just have a pointer

Hey All,
I'm trying to send immutable class objects to a thread, and am
having trouble if the object is one of several variables sent to
the thread. For example, I have a Message class:
class Message { ... }
and I create an immutable object from it, and send it to another
thread:
OK, I found a couple of solutions, though if anyone can tell me
something better, I would love to hear it.
By making an alias to a rebindable reference, the receive() was
able to create the tuple. So I renamed the class MessageType:
class MessageType { ... };
and then made a Message an
I got the OK to submit the D library to Eclipse Paho. So,
hopefully within the next few weeks there will be a Paho
incubator project for the D language client.
