Hi Shawn,

My opinion is that even though the "@" operator should be deprecated in
further along the line removed, it should not be repurposed for anything,
it has too much legacy imho.

While a shortcut might be a good idea, I personally favour the $this->var
syntax just for muscle memory if nothing else.
