Well, more like a quick hack...
http://www.algonet.se/~afb/d/javastring/html/class_string.html
http://www.algonet.se/~afb/d/javastring/html/class_string_buffer.html

But it does cache hash and utf32 ?
Java "char" was replaced with "dchar".
StringBuffer is thread-safe (synchronized)


I found it to be an interesting class exercise, maybe you'll do too...
http://www.algonet.se/~afb/d/javastring/html/_string_test_8d-source.html

It's not really safe, since toString returns a reference to the internal
string which you can the mutilate to your hearts content. But otherwise?


For other, more advanced, string classes see the Mango or Dool projects.

So right now it only works with char[], which should be plenty for this.
It's not like D *wants* a string class anyway, with the built-in arrays.

PS. setCharAt is kinda expensive, with D strings. Those are the breaks.

     And, yes, I used '+' for concatenating strings... This was Java. :-)
