Currently calling write() on a Tid prints:
Tid(std.concurrency.MessageBox)

In earlier versions this used to be:
Tid

In either case, this isn't much information. I think it would be useful if toString was overloaded and returned a string with some sort of unique thread ID, e.g.:

writeln(spawn(&test));  // Tid(0x0001)

This could make it easier to debug some types of threading problems without having to use a debugger.

Hmm it looks like there isn't such a thing as a cross-platform thread-identifier (at least not in Druntime).

Personally I like the idea of having named threads, where the name would be stored in a Tid. So you could do things like:

spawn("workThread", &func, args);

where the first pointer argument is the function. It might help with debugging, e.g. inspecting a Tid of a LinkTerminated exception could tell you which named thread threw the exception.

Nevermind, there's actually m_addr, which is a uint on Windows and pthread_t on Posix (a pointer to _opaque_pthread_t).

So I think core.thread.Thread should expose a getThreadID() function which
returns m_addr, and then Tid can expose this function internally and also use
it for toString().
