Proposed resolution:

Alter the list of constructors in both [futures.task] and in [futures.task.members] as indicated:

template <class F>
explicit packaged_task(F f);
template <class F, class Allocator>
explicit packaged_task(allocator_arg_t, const Allocator& a, F f);
explicit packaged_task(R(*f)(ArgTypes...));
template <class F>
explicit packaged_task(F&& f);
template <class F, class Allocator>
explicit packaged_task(allocator_arg_t, const Allocator& a, F&& f);

Moved to Tentatively Ready after 5 votes.

[ 2010-10-22 Howard provides wording, as requested by the LWG in Rapperswil. ]

[ US-207 Suggested Resolution: ]

Review the constructors for packaged_task and provide the same ones as function, except where inappropriate.

Addresses US-207

The constructor that takes R(*)(ArgTypes...) is not needed; the constructor that takes a callable type works for this argument type. More generally, the constructors for packaged_task should parallel those for function.
