One thing I'm not clear on is why Rust has both a "ref" keyword and an & operator? For example, in match arms I seem to need "ref" instead of & but I'm not sure what the difference is supposed to be.

Ref keyword versus &

Now that match ergonomics is stable, you can just pretend that ref doesn't exist, and your life will be better

(And I'm filing issues to have compiler suggestions also pretend that it doesn't exist.)
