Thanks, I missed that.
This isn't really what I was getting at though. If we are making a
substring of a String which is already small, then copying it seems
less efficient than referring to it. But if we make a small substring
of a very large String then copying it might often be better -- if if
the "small" is only relative. For instance a 1K substring of a 1M
String "should" (if we had perfect knowledge) be copied if it is the
only thing keeping the String alive.
