to it. Whether Go memory is pinned is a dynamic property of that memory
region; it has nothing to do with the type of the pointer.

Go values created by calling new, by taking the address of a composite
literal, or by taking the address of a local variable may also have their
memory pinned using [runtime.Pinner]. This type may be used to manage
the duration of the memory's pinned status, potentially beyond the
