The "callable" part is do-able, the rest isn't. The predicate may accept an arbitrary set of arguments via the "*args" and/or "**kwargs" syntax, and pass these on to some other function. Exactly *which* function may be the result of an arbitrarily complex expression. Or it may not even call another function, but just use the arbitrary set of arguments in an arbitrarily complex manner. IOW, determining in advance what will or won't work is actually impossible. -- http://mail.python.org/mailman/listinfo/python-list
