[ExpHP]

assert_eq!(3i32, &3i32);

On latest nightly:

  = note: expected type `i32`
             found type `&i32`
  = note: this error originates in a macro outside of the current crate (in Nightly builds, run with -Z external-macro-backtrace for more info)

To learn more, run the command again with --verbose.

Notice in particular the suggestion *assert_eq!(3i32, &3i32).

This doesn't happen on beta. Not sure if it's a regression or if the help hint is simply a recent addition.
