Subject: [PATCH] Address dom96/Araq opinions in
 https://github.com/nim-lang/Nim/pull/9922 Updating accessors are also
 provided since the idea of this change is to allow "updating" operations
 external to the module which are by their very nature closely tied to module
 internals (as well as to OS interface details).
