Hi, I have a generic class that needs to downcast from a base class to a template class. The template class can use virtual inheritance or not. When the derived class use virtual inheritance I need to use dynamic cast, but not on the other cases. I'm wondering if a new downcast function that will take in account these facts would be of interest in Boost. clase B {...}; class D : public B {...}; class DV : public virtual B {...}; B* ptr; ptr= new D(); D* dPtr = downcast<D*>(ptr); // uses static_cast as is_virtual_base_of<B,D>::type is false ptr= new DV(); DV* dPtr = downcast<DV*>(ptr); // uses dynamic_cast as is_virtual_base_of<B,DV>::type is true What would be a good name for this downcast function?
