I am requesting a formal review of my switch_ function template. The implementation docs and tests are available in the vault. http://tinyurl.com/yvssgx
Should this be part of a more general metaprogramming library containing "runtime construct generators?" I can imagine such generators as overload_set, while_loop, if_statement...
What would overload_set do? while_loop. Is this what you had in mind? template<bool> struct while_impl; template<> struct while_impl<true> { template<class Condition, class F, class T> struct apply { typedef typename F::template result<T>::type result; typedef typename while_impl< mpl::apply<Condition, result>::type::value >::template apply<Condition, F, result> next; typedef typename next::type type; static type value(F f, T& t) { result r(f(t)); return(next::value(f, r)); } }; }; template<> struct while_impl<false> { template<class Condition, class F, class T> struct apply { typedef T type; static type value(F, T& t) { return(t); } }; }; I can't think of any use for if_statement that isn't easier using if. mpl::for_each already handles looping over a sequence.
