Perhaps it might be possible to do some compile-time/run-time lambda
(similar to Boost.Lambda for runtime, and MPL's lambda), so you could do
something like:

mpl::for_each<my_list> (my_function<_>(s));

It would then transform the function call "my_function<_> (s)" into an
instantiated function object of the kind suitable for mpl::for_each.

That would collapse the 7 or 12-line solution to one line. :)
