Agreed. I know I'll be jumping on the bandwagon as soon as auto becomes mainstream in my two main
compilers, MSVC and GCC. So this is a compelling argument. But would it even be possible to keep the
"smart result" (either convert<>::result or optional<>) and auto compatibility? If (as I suspect)
not, this would seem to necessitate different syntax for value/throw and functor.
