Description
Here Clippy could suggest to replace exact_chunks_mut with exact_chunks:
#![feature(exact_chunks)]
#![allow(unused_variables)]
fn main() {
let mut data: [u8; 7] = *b"abcdefg";
let t: u8 = data
.exact_chunks_mut(2)
.map(|ch| ch[0] + ch[1])
.sum();
}

Research direction
Start by reproducing the example in a Rust nightly environment and inspect Clippy's existing lint implementations for iterator method suggestions. The work is done when Clippy recognizes the exact_chunks_mut case and suggests exact_chunks without changing valid behavior.
