The updated dstructors manual is [here](https://nim-lang.github.io/Nim/destructors.html)
Some notes I gathered: 1) [=sink](https://nim-lang.github.io/Nim/destructors.html#lifetimeminustracking-hooks-eqsink-hook) can be omitted, the compiler can it infer it for you but you still need to declare =destroy and =. 2) In =destroy you no longer need to set to nil the pointer after freeing the resource (recent change). 3) [sink inference](https://nim-lang.github.io/Nim/destructors.html#sink-parameter-inference) need to be turned off in some cases with closures, else the compiler errors (sorry don't know the specifics). This is a place better documentation is needed, but people in #nim helped me figure this out.
