No. There is not std::list constructor (which is needed here) to convert
a list<Derived*> to a list<Abstract*>.

Yes. shared_ptr has support for an appropriate conversion constructor.

But you can do:

void doAbstractOnce(Abstract* abstract) { ... }

std::list<Derived*> list;
std::for_each(
list.begin(), list.end(),
&doAbstractOnce
);
