What's the idiomatic way to concat a bunch of slices?
Raw
append.go
// Assume the following variables...
// r [][]string
// s string
// p []string
//
// Problem: append to r the []string x where x is p[1:] + [s] + p[:1]
// 1. Do crazy appends
r = append(r, append(append(append(make([]string, 0), p[:i]...), s), p[i:]...))
// 2. ?

a = append(a[:i], append([]T{x}, a[i:]...)...)
