I'm no C++ expert, but:
Where is the parallel aspect? It looks more like a shorthand to spawn a
thread to evaluate an expression/closure/function call, and then wait on it
using .join().
The "closure"-like aspect (be able to pass expressions to be evaluated
somewhere else) looks like a bigger feature then that threads are now
grouped under namespace std.
I'm note sure we are actually witnessing something like the parallel for you
talked about earlier? Are you sure?
