Gambit's unquote-splicing ignores the end of improper lists (when
splicing into the middle of a list):
> `(hello ,@"hmm" well)
(hello well)
> `(hello (unquote-splicing '("hmm" . "and")) well)
(hello "hmm" well)
Scheme-48 and Chicken throw an error in this case. Is there a reason
an error should not be thrown?
