From the documentation:

- ["foo", "bar"].iter().map(|s| s.to_string());

+ ["foo", "bar"].iter().map(|&s| s.to_string());

I feel like saving 10 nanoseconds from the formatting machinery isn't worth asking the programmer to insert extra & / * noise in the vast majority of cases. This is a pedantic lint.

Downgrade inefficient_to_string to pedantic

From the [documentation](https://rust-lang.github.io/rust-clippy/master/index.html#inefficient_to_string):

I feel like saving 10 nanoseconds from the formatting machinery isn't worth asking the programmer to insert extra `&` / `*` noise in the *vast* majority of cases. This is a pedantic lint.
