Thanks. So basically, there's no memory benefit or performance benefit to
using nil slices over empty slices -- it's ultimately just a matter of how
you want them to serialize JSON or get written to databases?

Running this:
emptyslice := []string{}
sh := (*reflect.SliceHeader)(unsafe.Pointer(&emptyslice))
fmt.Printf("empty slice cap = %d\n", sh.Cap)
fmt.Printf("empty slice len = %d\n", sh.Len)
fmt.Printf("empty slice uintptr = %v\n", sh.Data)
Output:
empty slice cap = 0
empty slice len = 0
