What do you think of the following macro that implementes this in
ISO
standard C++ while keeping the above C++0x-like syntax by wrapping
it
within a preprocessor sequence?
BOOST_CPP0X_FUNCTION(
   (template)( (std::CopyConstructible)(T) )
       (requires)( (Addable<T>) (Assignable<T>) )
       (precondition)( (first) (last) )
       (postcondition)(total)( (total == result) )
   (T) (sum)( (T*)(first) (T*)(last) (T)(result) ) ({
       for (; first != last; ++first)
           result = result + *first;
       return result;
   }) )
This reminds me about the time when I tried out LISP programming, but 
didn't like it. To me it looks like there is very little C++ left in 
there, sorry.
