This seems to cast out the type inference present in BLL. I think that's one of the nicer concepts in the lambda library, and a real boon to programming. In my limited experience with SML/OCaml, type inference seems a better, safer, and more convenient way to program, albeit requiring a lot more compiler intelligence. As BLL shows,

this is quite possible, though perhaps limited, with existing C++.
How about: unsigned long n = std::accumulate( xs.begin(), xs.end(), 0UL, auto(long lhs, const auto& rhs) // inline fn with no name. { return lhs + rhs.count; } ); ? Jonathan
