The way to get a high performance string parser in D is to take

wrong.
Java's substring() does not copy the text, at least in the official JDK
implementation. Unfortunately, it doesn't specify this behavior as part
of the String API.
But, I assume, it will allocate a new instance of String even though the
content point to the same data?
