https://dlang.org/spec/declaration.html#Typeof

it's another 'this' that has not the same semantic as the 
reference holder.
Just like 'const' can have 3 meanings, 'this' also:

- this.member: typical usage, it hold the instance reference
- void foo(this T)(): template this parameter, T is typeof(this) 
where the template is used.
- typeof(this): you can use it in static func, this 'this' is not 
the 'this' instance.
