That detail becomes visible as soon as one variable changes an element and another variable unexpectedly sees the same change. <code>slices.Clone</code> gives the copied slice separate element storage with a single call.</p> <p>The copy is shallow. That makes it a clean fit for slices of numbers, strings, and value-only structs, but nested maps, slices, pointers, and other reference-like values still need deliberate handling.</p>
