The point here is that person1 and person2 are not instances of the same

Templates cannot be used to add non-static members or virtual

Templates cannot add functions to interfaces.

Thanks, Ali! :)

But uncomment the override and it fails.
That's because Templates cannot be used to add [...] virtual functions

Andrej Mitrovic:
Agreed. Can you file a bug report?
Sorry, but I don't understand the topic enough yet (I don't know why templated
methods can't be virtual), so I leave the bug report to someone else that's
able to write something meaningful in the bug report :-)

why does SList.insertFront have a complexity of O(log(n)) ?

Good question! It certainly is not the code's fault, as that's O(1) for
single elements and O(m) for ranges. File it to Bugzilly, I guess.

I know this is just playing dangerous, still tempting to use for things like
plugins ,member interfaces or even struct interfaces.
It is easy to do without unions because delegates have ptr and funcptr pointers
with just a swap of pointers.
Are .ptr and .funcptr really needed to be writeable?

First of all, they can. But it's a shitload of extra work, and requires
that compilation be mixed up with linking.
Whenever a templated method is used from any subclass, it has to be
generated
