Comment (by jeff):

 Fix a typo in the second code block: it should be enable_if_c instead of
 enable_if.
 also this_type is nullary_function<void()> or nullary_function<R()>
 (depending on the specialization).

 {{{
       using this_type = nullary_function<void()>;
       template<typename F, typename = typename
 boost::enable_if_c<!boost::is_same<typename decay<F>::type,
 this_type>::value>::type>
       nullary_function(BOOST_THREAD_RV_REF(F) f):
       impl(new impl_type<typename
 decay<F>::type>(thread_detail::decay_copy(boost::forward<F>(f))))
       {}
 }}}
