I don't find a constructor of function from a rvalue functor.

But I find an assignment

This seems confusing. What am I missing?

I don't have a standard but this is in sync what you describe:

http://en.cppreference.com/w/cpp/utility/functional/function/function

http://en.cppreference.com/w/cpp/utility/functional/function/operator%3D

confusing indeed.

Anyway, trying to:

#define BOOST_THREAD_VERSION 4

#include <boost/thread/future.hpp>

#include <functional>

int main()

{

  boost::packaged_task<void()> t;

  std::function<void()> f2;

  f2 = std::move(t);

}

gives exactly the same compilation error:
