描述

There are some intrinsics that there should be no reason to call. For example core::intrinsics::size_of. This intrinsic is exposed by the safe function core::mem::size_of which should always be called instead.

I would like to suggest a Clippy lint that notices calls to no-reason-to-call intrinsics and recommends the right stable or safe wrapper to call instead.

研究方向
Research the list of intrinsics that have stable or safe wrappers, starting with core::intrinsics::size of as mentioned in the issue. Look at existing Clippy lints for examples of how to implement a new lint (e.g., in clippy lints/src/). Check the comments in the issue for additional intrinsics suggested by the community. Define a lint that detects direct calls to these intrinsics and suggests the corresponding safe wrapper.
