The following fails to compile on emacs 26 but compiles on emacs 25:

  (lambda (obj) (with-slots (message) obj (message "")))

It fails with:

  Eager macro-expansion failure: (invalid-function ((slot-value object (quote message))))

It appears to be substituting the `message` function name with
`(slot-value object 'message)`.
