Hello,

Is there a way to print the type returned by a metafunction

   typedef some_metafunction<T>::type result_type;

during compile-time (probably via triggering a compilation error).

I almost recall some sort of static assertion  (mpl ?) to do this.

If all you want is an error you could do typedef typename some_metafunction<T>::result_type error[0] or something like that. Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
