Playing the devil's advocate:
Yes, it does so by assigning a slice from `c` to a slice from
`b`.
Let's try to explain why this:
b = c[1..4];
changes what b refers to, while this:
b[] = c[1..4];
copies.
Well, if you assign a slice to a slice, that means 'copy
elements'.
But if you assign a slice to <what b is>, that means change the
reference.
