[Boost-users] [result_of] Simple question

Morning All It's first thing in the morning for me, so maybe my neurons aren't warmed up, but I was surprised this doesn't work. #include <boost/utility/result_of.hpp> #include <boost/function.hpp> typedef boost::function<int(char)> my_function_type; typedef boost::result_of<my_function_type>::type my_return_type; Doesn't Boost.Function support 'result_of', or am I missing something obvious? If not, is there some other idiom for this, bearing mind that 'my_function_type' might be a Boost.Function, or a true function, or a Boost.Bind? Thx, - Rob.
