"ensure-function" is best defined like this: (defun coerce-function (sym) (coerce sym 'function))
No, it's not. (COERCE ... 'function) takes literal lambda expressions, but ENSURE-FUNCTION should not.
I have probably not understood how to use ensure-function. So I looked in to the functions.lisp file to check it out. But, I'm still not sure what would be wrong about sending ensure-function a literal-lambda expression. Explain please :) It would fit it's name better if it took a lambda list, though.
Another function I found is disjoint. And according to google: Two sets are disjoint if they have no element in common. To me, that is like XOR, while Alexandrias definition of disjoint, is more like OR. Am I wrong again?
