at a higher level e.g. at the method or even class level. Use your judgement.

There are also cases where the compiler simply refuses to accept an assignment
or cast of any kind, because it lacks the information to know that the types are
OK. In such cases, you can use
the [`Types.forciblyCast`](libs/core/src/main/java/org/elasticsearch/core/Types.java)
