As a self contained template the pointer itself works well but I am having trouble getting it to…

How to handle implicit and explicit type conversions between const and non-const fancy pointers?
Given the type definitions
using ConstHandle = MyEntity const*;
using Handle = MyEntity*;
it is possible to conduct the following type conversions:

ConstHandle → Handle (explicit via const_cast)
Handle* →…
