When `v` comes into scope, a new [vector] is created, and it allocates space on
[the heap][heap] for each of its elements. When `v` goes out of scope at the
end of `foo()`, Rust will clean up everything related to the vector, even the
heap-allocated memory. This happens deterministically, at the end of the scope.

We'll cover [vectors] in detail later in this chapter; we only use them
here as an example of a type that allocates space on the heap at runtime. They
