There was a problem hiding this comment.
@hvitved Box patterns are probably not very often used, but it might be easy enough to just add support for them. All other new MISSING annotations are related to tuples, slices and arrays.
Thanks to co-pilot for generating the examples

Thanks to co-pilot for generating the examples.

I had to drop the sample code about "const block patterns" because that feature has been removed from Rust.
