I love Go, my favourite language. But I've been bitten before by passing slices around and then finding out that they got disassociated and are now pointing at two different backing arrays without telling me.

I kinda know enough now to avoid this, but I have to be careful and remind myself it's a possibility.

I'd love some built-in method to be able to tell whether altering a value in slice A will also alter the value in slice B (i.e. whether A and B are referring to the same backing array). As far as I'm aware there's no easy way of doing this in Go.
