The "alias newThing = x;" syntax is not allowed with alias this. 
It's the only exception.

You have to use

alias getSingleton this;

I've tried and fail to do what you want, even with a templated 
class + eponymous trick.

"this" is for an instance of class (or struct). There is no 
instance of define an alias at that time. I am not sure, but you 
can check "opCall" function as static for this. Give it a try at 
least.
