Yup, binding to something does indeed work. Thanks much for the help.

I recommend that application packages use kw.

BTW for completeness the ((...)) syntax can probably also be made to 
work if you bind to something:

(kw:findall '?x '(and (hobbit ?x age ?a) ((< ?a 50) t)))

Assuming < returns t. 

You might also find there is a Prolog predicate version:

(kw:findall '?x '(and (hobbit ?x age ?a) (< ?a 50)))

Although you may have to watch your packages again.
