It can't be: 'private this()' because that conflicts with the use 
of the word 'this' that is associated with a constructor.

'private (this)' makes perfect sense to me.

First, the word 'this' is already associated  "to the object, 
class, or other entity of which the currently running code is a 
part." - https://en.wikipedia.org/wiki/This_(computer_programming)

Second. The exact same syntax can be used for class or struct.

One could argue that 'private (this)' and 'private this()' are 
too close syntactically, and could cause confusion. I wouldn't 
disagree. But I'd be fine with it, since I'd be using it so 
often, it'll be programmed into my muscle memory ;-)
