Re: [boost] [typeof] is T registered?

I am wondering if it is possible to add some functionality so user can

tell

if a type is in the database of registered types during compilation. It may be there already of course.

template <typename T> struct Func{ //one possible use case typedef typename boost::mpl::eval_if< boost::is_typeof_registered<T>, // true if T is registered typeof_operation<T>, // use BOOST_TYPEOF try_something_else<T> >::type type;

};

Its not critical, but I thought it might be useful while libraries are adding the typeof functionality. Also might help me in the "[typeof] gcc and typeof in function return type" thread.

Doesn't the workaround I provided help? Regards, Arkadiy
