huh. very cute. in the past, i had an idea for terser lambda syntax, similar to C#'s expression body functions - which i did end up implementing in clang:

    auto sum = [](auto a, auto b): a+b;

but this is something else. i didn't think i'd like it at first, but actually i think i might be coming around to it. the.. dollar syntax is regrettable, although it's not a show stopper.
