Clippy nightly build broken #3708
Description
Due to rust-lang/rust#57907 and rust-lang/rust#57726 Clippy fails to build with the latest Rust nightly/master currently.
If you rely on using the nightly Clippy component, you can try using the last working nightly: nightly-2019-01-26. Please also be aware that Clippy has been available on stable Rust for a while now and is guaranteed to always work.
