The problem with "alias this" is that it was designed to emulate
inheritance, but was *diverted*, specifically, to emulate
"implicit casting instead".
I think the results speak for themselves how well that worked...
As a matter of fact, there are more than a few classes where I
wish we could deprecate the static alias, and re-force explicit
cast.
