Improve some inference diagnostics - Properly point out point location where "type must be known at this point", or else omit the note if it's not associated with a useful span. - Fix up some type ambiguity diagnostics, errors shouldn't say "cannot infer type for reference `&'a ()`" when the given type has no inference variables. |
