The usual way would be to return an object.
r = GrailSearchResult()
r.search = ...
r.holy = ...
r.grail = ...
But if the "usual Python way" of representing a compound value seems too
heavyweight, the "collections.namedtuple" type supports objects that all
have the exact same set of attributes. It is implemented as a tuple
whose members can also be accessed by attribute names like ".holy" and
".grail" but which is stored as a compact read-only tuple.
