There are places throughout the standard packages where extra copies happen
due to []byte <-> string conversion (like strings.Join(),
os.*File.WriteString() etc.) I am assuming they don't use an unsafe-magic
way to make aliasing strings and []bytes because they don't want people to
shoot them

I found myself writing code like this:
s := make([]byte, len)
for i := 0; i < len; i++ {
// fill in s with stringy goodness
}
return string(s)
Does this reuse the memory in s for the string, or does it allocate new
memory and copy? Or does escape an
