`alias this` suffers from being under-specified. In an attempt to fix that, I 
discovered it runs smack into multiple inheritance land, something I've tried to 
avoid. Worse, its implementation does a half-baked job of multiple inheritance, 
and backwards compatibility interferes with fixing it.

To move forward with it, it would have to be abandoned in its current form and 
completely redesigned.
