We should keep this test until we implement unstable sort lint for sort_by (SortingKind::ByCmp)

Should we add a test for chars as well?

Also test cases for types that deref to a slice of primitives.

I believe Vec derefs to a slice, so I think the tests already have that last bit covered, unless I don't understand what you're getting at.

No, you are correct. My bad.

@JarredAllen Hey should we add test cases for list of tuples such as: vec![(2, 1), (1, 3), (3, 2)]

@krishna-veerareddy I added test cases for a list of tuples and also for one of arrays.

Can we extend this to include a list of static strings such as ["ab", "bc", "ab", "cd"]. This would qualify for an unstable sort, right?

That should be a Ref of a Slice of a Str
Can we rename this function is_recursively_primitive_type and stick it in utils somewhere?

I would avoid using multiline comments and instead just use lots of //, it's pretty standard style in Rust or at least in this codebase.

For some reason, cargo dev fmt seems to insist on changing those comments to be multiline ones.
