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 #include <functional>

int main() { boost::packaged_task t;

std::function f2; f2 = std::move(t); }

gives exactly the same compilation error:

I get the same kind of error for gcc-4.8.0 and clang-3.2. I suspect that either we are missing something basic or there is a issue on the standard specification and the standard library implementors have not identified it while implementing these operations. Best, Vicente
