Unignore closure-bang. This test was ignored long ago in https://github.com/rust-lang/rust/pull/20578/ when the syntax for closures was changed. The current status is that a closure with an explicit `!` return type will trigger the `unreachable_code` lint which appears to be the original intent of the test (https://github.com/rust-lang/rust/pull/16836). A closure without a return type won't trigger the lint since the `!` type isn't inferred (AFAIK). This restores the test to its original form. 2023-04-15 21:43:20 +00:00			`let x = \|\| -> ! { panic!() };`

Update dead-code-closure-bang This stdlib function went away, so update it to use current syntax. 2015-06-12 18:15:57 +00:00			`println!("Foo bar"); //~ ERROR: unreachable statement`
