Summary:
The code was passing pointers around, expecting they would be not null.
In c++ it is possible to convey this notion explicitly by using a
reference instead.
Not all uses of pointers could be converted to references (e.g. one
can't store references in a container), but this will at least make it
locally obvious that code is dealing with nonnull pointers.
