There are no requires corresponding to F of std::function.
[ 2009-05-01 Daniel adds: ]
1070 removes the second constructor.
[ Batavia (2009-05): ]
We agree with the proposed resolution. Move to Tentatively Ready. If issue 1070 is accepted, the changes to the second constructor in this issue are moot.
[ 2009-07 Frankfurt: ]
Constructors have no definition.
Proposed resolution:
Correct as follows in 22.10.17.3 [func.wrap.func] (class definition)
template<class F, Allocator Alloc> requires ConstructibleWithAllocator<F, Alloc> && call=Callable<F, ArgTypes...> && Convertible<call::result_type, R> function(allocator_arg_t, const Alloc&, F); template<class F, Allocator Alloc> requires ConstructibleWithAllocator<F,Alloc> && call=Callable<F, ArgTypes...> && Convertible<call::result_type, R> function(allocator_arg_t, const Alloc&, F&&);
