Defined in header <functional>
template< class R, class... ArgTypes, class Alloc > struct uses_allocator<std::function<R(ArgTypes...)>, Alloc> : std::true_type { };		(since C++11)

This specialization of std::uses_allocator informs other library components that all objects of type std::function support uses-allocator construction, even though they do not have a nested allocator_type.
