I guess it wouldn't be an insurmountable task to overload csv() on the number of arguments, internally calling list_of(), and returning its results. That's approximately how ref_csv() and ref_list_of() relate to each other.
That sounds sensible. I think there should be such a function.
Tentatively I made the change here: http://svn.boost.org/svn/boost/sandbox/statistics/support/boost/assign/list_... Here's an example: { int a = 1, b = 2 ,c = 3; std::vector<int> vec = list_of(a).csv(b,c); BOOST_ASSERT( vec[0] == 1 ); BOOST_ASSERT( vec[1] == 2 ); BOOST_ASSERT( vec[2] == 3 ); } which can be found here http://svn.boost.org/svn/boost/sandbox/statistics/support/libs/assign/exampl... Note that list_of(a).csv(b,c), as opposed to csv(a,b,c), has the advantage of returning a reference. There is a separate thread on how to create an empty list, which would allow something like empty_list_of().csv(a,b,c), which would be more elegant.
