The 'alias this = A' syntax did appear for one release as an

Having two syntaxes for alias makes everything looking worse and is an
unnecessary noise.
'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
}
