'alias this' is different from normal aliasing. The 'alias ... this' 
syntax should be replaced, but we haven't agreed on by what. I think 
Timon Gehr's opThis solution is best:

Using the opThis identifier (or similar) avoids having to introduce a 
separate 'get' property function when you need to add const qualifiers 
to the forwarded symbol, or do some processing first.

P.S. As I noted in that thread, the suggested syntax for forwarding 
constructors is not so ambiguous, it should be:

class D : C {
     alias this = super.this;	// note .this to name base ctor
}
