'cause `alias this` is *not* a tool that can be used to emulate

automagically paste the code.
Thanks for the reply. Is there any reason for disallowing this?
AFAIK, the alias this guarantees that the interface provided by
Test!T is a superset of the interface provided by T. And, when T
= Duck, T provides everything required by IDuck. Couldn't the
compiler check while instantiating that Test!Duck provides all
methods required by IDuck?
