Have you considered making deref the default instead and requiring moves to use an

Basically, from this hypothetical syntax to current one:
- x => &x
- mut x => &mut x
- move x => x
One could even make the & implicit in parameter types in function declarations unless the
"move" keyword is used, so we would have (new => old syntax):
- fn(self, ...) => fn(&self, ...)
- fn(mut self, ...) => fn(&mut self, ...)
- fn(move self, ...) => fn(self, ...)
I like this proposal, because afaik it matches the common use case.
Also, it would make things easier to learn, understand, and use, for people not
used to move semantics (even less to it as default / implicit case). I do
struggle with move; making it explicit would help (also when reading it other
people's code).
