Since there is a thread running concurrently about the implications of
virtual destructors, I thought I would point out that the code below
requires that the destructor of the base object be virtual. If the
destructor is not virtual, there will be a run-time error when delete
expression is invoked against at pointer whose static type is the base
type but dynamic type is the derived type.
MostDerivedType * mdt=mostderived_cast<MostDerivedType>(_p);
// mdt is "leftmost" pointer
