If the traits were polymorphic in the index type (instead of always
expecting an integer), then one could use them to make hash tables use
vector syntax (e.g., `hash["foo"] = 1`)... Ruby does that, for
example. So something like bitset (with integer indices) isn't the
only example.
Not sure whether we want to go that way, though...
Note that the traits in the blog posts are parameterised by the index type:
trait Index<I, E> { fn index<'a>(&'a self, index: I) -> &'a E; }
Etc.
