Looks cool!

I'm to strapped on time to try it out right now, but I will when I get 
the chance.  I do have a couple questions and a comment based on the 
documentation:

- Is toString() the same as toUTF8()?  If so, I'd like to see something 
in the documentation to say they are the same.
- Are there plans to extend this to act as a string manipulating library 
as well as a string type, adding stuff from phobos like toUpper(), 
toLower(), capitalize(), split(), etc?  That would be cool.
- Seems like it would be handy to have functions for converting to C 
style null terminated strings.  Something like char* toUTF8C() and 
wchar* toUTF16C().

This looks like a very useful string type.  I just hope that if people 
like it, it becomes part of the standard library or some such so that 
newbs aren't caught by indexing/slicing in the current string-as-array 
approach.  Anyhow, thanks for doing that.
