For example:

https://books.google.de/books?id=5_eoCwAAQBAJ&pg=PA104&lpg=PA104&dq=dlang+rely+destructor&source=bl&ots=p33jiNUKBq&sig=yw1ymCzaRaueQ8yDDMjP75iRDYI&hl=de&sa=X&ved=2ahUKEwjosrGlhePeAhVrgM4BHcU6DEAQ6AEwBXoECAMQAQ#v=onepage&q=dlang%20rely%20destructor&f=false

@book{parker2015learning,
   title={Learning D},
   author={Parker, M.},
   isbn={9781785289347},
   url={https://books.google.de/books?id=5\_eoCwAAQBAJ},
   year={2015},
   publisher={Packt Publishing}
   page=104
}

But yeah... I had troubles to find such a clear statement on 
dlang.org too...
