Thanks!!! Very helpful blog post!!
So, in proc, the slice header is copied, then an entirely new array is
created - []byte{5,6,7,8} - and the slice header copy is set to point at
that new array, and then discarded, whereas in proc 2, the slice header is
not reset, and so still points to the original array?
