And Walter is already expressing regret at allowing `alias this`.  I
used to love `alias this`, and still use it in many of my projects, but
over time, I'm also starting to agree with Walter that it was a mistake.
Implicit conversions are generally not a good idea, except in very
narrow, well-defined cases. They are convenient, but lead to problems in
long-term maintenance.
