It seems to be somewhat similar to std.parallelism (http://dlang.org/phobos/std_parallelism.html)
I have seen that before, didn't know if there was anything closer with the task scheduler and worker threads described in the documentation for TBB, or if that was the closest thing.
I see that it does have a TaskPool and worker threads within that, but they seem to be only using a shared queue and individual worker thread queues. So a task spawning another task does not really have some of the efficiency benefits that it does in TBB (where the worker threads maintain a dequeue instead). I also didn't see any mention of task stealing, but maybe it does that internally. Not sure. I can take a look at the code for it I suppose.
