improve liveness so it reports unused vars / dead assignments doesn't warn about pattern bindings yet though 2012-05-23 20:53:49 -07:00			`fn test() {`
Update compile fail tests to use isize. 2015-01-08 21:54:35 +11:00			`let v: isize;`
Compiler error messages: reduce assertiveness of message E0384 This message is emitted as guidance by the compiler when a developer attempts to reassign a value to an immutable variable. Following the message will always currently work, but it may not always be the best course of action; following the 'consider ...' messaging pattern provides a hint to the developer that it could be wise to explore other alternatives. 2021-04-12 23:29:09 +01:00			`//~^ HELP consider making this binding mutable`
