Well, as you said the simpler way is to use the size function provided :-). Also your size implementation is somewhat unsatisfying in the sense that it uses empty which internally uses the library's size (meta)function. [snip] Well, as I said, I was trying to do "something like that". My actual

I guess fusion::transform would be appropriate; however, I want to accummulate the results; so maybe I should be using fusion::fold. Anyway, I was just trying to figure a way to stop the terminal. I would have thought: template<typename Seq> int f(Seq const&); with termination caused by: int f(fusion::nil) would solve the problem; however, pop_front(list<int>(1)) apparently is not fusion::nil; hence, my problem. Anyway, Tim Moore in a private email proposed the attached solution, which seems simplest. BTW, I did try boost::fusion::iterator_range; however, it didn't have next defined on it :(. Thanks to Tim! -regards, Larry
