Hi,

What is the rationale for when_all to return future<vector<future<R>>>
instead of future<vector<R>>?
What is the rationale for when_any to return future<vector<future<R>>>
instead of future<pair<size_t, R>> ?

What about adding when_all overload for containers that return the same
container type instead of a vector?

*template <typename C>**
**future<see below> when_all(C c);**
*Requires: C is a Container, C::value_type is of type future<R> or
shared_future<R>.
Return Type: A future having the same container type but with a
value_type R.
Returns: A future having a container with all the future values.

Best,
Vicente
