Detailed Description

template<typename ResultType>
class PackagedTask< ResultType >

Corresponds somewhat to std::packaged_task.

Like packaged_task, this holds a function acting as a promise. This type is mostly just the shared state and the call operator, handling the promise & continuation logic.
