There was a problem hiding this comment.
To be clear, the case where we have:
" var x = (A<@Nullable String> & Serializable) o;",
" x = new B();",
Should have no error, right? Should we encode that test case just to make sure we never regress that?

you're right, and i think we will get a false positive on that test for now (since for some reason var-declared variables don't get types with all the right annotations). i'll add tests and open an issue for outstanding tasks, but will fix in a subsequent PR

Intersection types may arise, e.g., as part of string concatenation. We handling of an intersection type for one scenario; broader handling definitely requires more testing and thinking.
