Well, you can, because you don't access object internals, but the 
point was exactly that extension methods can make programs harder 
to read.

It is not an extension. It is a function returning a reference 
object that holds a pointer to the object and the new interface 
methods you want it to have. It is explicit so it does not make 
programs harder to read.
