There are two types of "no RTTI". Everything except dynamic_cast and typeid 
on polymorphic types works; or everything involving RTTI fails in compile 
time.

The practical difference is that there is code that works on the first type 
of "no RTTI" (get_deleter, function<>::target) and fails on the second.
