I was thinking about the case where someone has a hypothetical custom
container Foo with perhaps only an at(i) function. Then it is easier
to provide specializations for the set(), get() globals, just passing
a pointer to the container into the graph algorithm, compared to
creating a new class with operator[](), and then also wrapping the Foo
object at *every* call site.
