I don't think the behavior matters much when we pass invalid code to
`eval'. OTOH it's important that we report it when byte-compiling it.

Chewing is just a crutch when nobody is regurgitating for you.

Not in XEmacs, which tests for listp, not sequencep.
I guess Stefan is trying to evolve Elisp into Clojure, or maybe
Python.
