If someone uses those two primitives in the context of that
particular algorithm, they'll likely to keep track of the capacity of
the vector saying how many things fit and the size counting how many
things are already there. You'll increment size when adding things
pushing and enlarge/reallocate when size = capacity. By then you'll
have "open coded" VECTOR-PUSH-EXTEND or C++'s std::vector::push_back
or whatever your preferred language calls it.
