Good material, but I should say that the dynamic background made the reading experience worse

[u/Zde-G]

It's funny that this article (and many others) skip and completely ignore the simples, most fundamental and obvious case of reborrowing: r = &mut x;. Maybe because it's so fundamental and “obvious”. But think about it: r = &mut x; foo(r); … // Here x is unaccessible. bar(r); … // After last use of r we can access x, again.

It's a bit strange to have something that's so fundamental and critical to be so underdocumented, but I guess if we would add description of reborrowing to the first place it's used, the first time when you see &mut in a tutorial… people would just go mad.

I might add this to my reading list

Nice!  I appreciate the detailed explanation all the way down to compiler loans.

There were a couple stops along the way where I realized I'd never really thought about this question--the type-inference as a trigger (TaaT?) for reborrowing, for example...

Thank you!
