if you're talking about libinput_device_get_keys(), you'll have noticed 
that it's deprecated and slated for removal.

again: what's the point of providing a set of all keys to the caller? 
What will the caller do with that set, other than checking the set for 
certain keys? (i.e. exactly what has_key() does, with error checking, 
type safety, no custom bit macros, etc.)
