It seems that the term "auto-dereferencing" applies only when the target to dereference is a method receiver, whereas it seems that the term "deref coercion" applies to function arguments and all contexts it needs to. I thought that a dereference does not always involve deref coercion, but I'm not sure: does dereferencing always use some Deref::deref trait implementation? If so, is the implementor of T: Deref<Target = U> where T: &U built into the compiler? Finally, it sounds natural to use the term "autoderef" in all the cases where the compiler implicitly transforms &&&&x to &x : pub fn foo(_v: &str) -> ...
