I don't think that meets Dirk's original goal though, which is "Does this
function exist in this package?" can() is a method (which means that you are
in a state of sin if you use it as a function) but it also works on methods,
so it answers the question "Is there a method of this name defined in this
class or any of its parents?"
The use of the word "function" makes me think that inheritance is not a
desirable property here, so even when using can() as a method, I'm not sure
it'll answer the question appropriately.
