Technically, it is an official anti-pattern to use `instanceof` on Language
Model classes. Yes, it works OK for the JDK implementation of
`javax.lang.model`, but it is not necessarily true for all other
implementations (with a known instance where it is not the case.)
The recommended solution is to either use visitors or test or switch on the
`ElementKind`.
That all being said, I accept this is in JDK code ... and now that we have
pattern-switch available ...
