--wip-- [skip ci] --wip-- [skip ci] get the generic text and put it int he suggestion, but suggestion not working on derive subdiagnostic refactor away from derives and use span_suggestion() instead. Show's the correct(?) generic contents, but overwrites the fn name :( x fmt drop commented code and s/todo/fixme get the correct diagnostic for functions, at least x fmt remove some debugs remove format remove debugs remove useless change remove useless change remove legacy approach correct lookahead + error message contains the ident name fmt refactor code tests add tests remoev debug remove comment 2022-10-23 08:52:59 -05:00			`// Issue: 103366 , Suggest fix for misplaced generic params`
