So when discussing the requested variadic fiber constructor, I will
tease apart the C++11 and C++03 cases. I feel pretty comfortable stating that the former is much more important than the latter.
Agreed, but at least the C++03 must support movables types.
does boost::thread support moveable types? if I look at the source code (C++03 equivalent to variadic arguments):
template <class F,class A1,class A2> thread(F f,A1 a1,A2 a2): thread_info(make_thread_info(boost::bind(boost::type<void>(),f,a1,a2));
The arguments are captured by boost::bind() which (as far as I know) does not support moveable types as arguments (in the example a1 and a2) - or do I miss something?
Right. Boost.Thread provides only a variadic version for copyables and doesn't support movable types in C++03 for the variadic version, but provides a constructor from a callable movable or copyable. template <class F> explicit thread(F f , typename disable_if_c< boost::thread_detail::is_convertible<F&,BOOST_THREAD_RV_REF(F)>::value , dummy* >::type=0 ); template <class F> explicit thread(BOOST_THREAD_RV_REF(F) f , typename disable_if<is_same<typename decay<F>::type, thread>, dummy* >::type=0 ); As I said, implementing perfect forwarding is not possible in C++03 (See Boost.Move documentation).
