When a local variable is promoted to a record type, and then an assignment statement is used to assign a record literal to that local variable, if the fields of the new record literal are not assignable to the fields of the promoted record type, that's not a problem; both the analyzer and front end agree that the local variable is simply demoted. But the spec implies that if the old and new record _shapes_ are the same, then a compile-time error will occur instead of a demotion. I've created https://github.com/dart-lang/language/pull/3613 to bring the spec in line with the implementations. This test demonstrates the current behavior of the implementations, and makes sure that it doesn't regress.
