Detailed Description

Effectively our own custom std::packaged_task<>, with copy semantics and letting us early set value to significantly improve performance.

Template Parameters:

class R

The return type of the callable which must be without parameters. Unlike `std::packaged_task<>`, this custom variant is copyable though each copy always refers to the same internal state. Early stl_future value setting is possible, with any subsequent value setting including that by the function being executed being ignored. Note that this behaviour opens the potential to lose exception state - if you set the stl_future value early and then an exception is later thrown, the exception is swallowed.
