Unlike other languages, in Go, switches themselves are not indented; it's just each case body which is indented by one level: switch foo { case "bar": baz() } As such, we shouldn't `@indent` for type_switch_statement nor expression_switch_statement, as otherwise inserted lines show up as: switch foo { // inserted with "o" case "bar": // inserted with "o" baz() } With the fix, the inserted lines are indented properly: switch foo { // inserted with "o" case "bar": // inserted with "o" baz() } I also verified that indentation on selects similarly works well. Thanks to Triton171 for helping with this fix.
