A setter on a non-Escapable type may have a dependency on both it's incoming 'self' and 'newValue'. If the 'newValue' dependency does not match the getter's dependency, then lifetime diagnostics will not accept the generated '_modify' accessor: error: lifetime-dependent value returned by generated accessor '_modify' To fix this, make sure that we don't (conservatively) infer a borrow dependency on 'newValue'.
