#![feature(lint_reasons)]
// If you turn off deduplicate diagnostics (which rustc turns on by default but
// compiletest turns off when it runs ui tests), then the errors are
// (unfortunately) repeated here because the checking is done as we read in the
// errors, and currently that happens two or three different times, depending on
// compiler flags.
//
// The test is much cleaner if we deduplicate, though.
// compile-flags: -Z deduplicate-diagnostics=yes

unsafe_code,
//~^ NOTE `forbid` level set here
//~| NOTE the lint level is defined here
