The special case in the spec is that you can take the address of a composite literal using the & operator. A composite literal is not, however, generally addressable, and the slice operator requires an addressable argument, so [3]int{1,2,3}[:] is invalid. This tutorial code and one bug report are the only places in the tree where it appears. R=r, gri CC=golang-dev https://golang.org/cl/5437120
