No. Wrong. The compiler issues an error because `kkk` is no longer in
scope. That has nothing whatsoever to do with the GC.

You should assume nothing happens to `kk` as a consequence of the Go GC. It
is true that the operating system will invalidate the page of memory
containing that var and ensure the page is zeroed before giving it to
another process. But that has nothing to do with the Go GC.
