Point at local similarly named element and tweak references to variants Point at the span for the definition of ADTs internal to the current crate. Look at the leading char of the ident to determine whether we're expecting a likely fn or any of a fn, a tuple struct or a tuple variant. Turn fn `add_typo_suggestion` into a `Resolver` method. 2019-10-14 19:20:50 -05:00			if let C1(..) = 0 {} //~ ERROR expected tuple struct or tuple variant, found constant `C1`
