A string literal is immutable, dchar[] is mutable.  These should work:

immutable(dchar)[] test = "test";
dstring test = "test";
auto test = "test"d;

wait, you thought char[] was an array?  You poor poor soul ;)

I predict we shall get 1-2 questions/claims of incredulity like this a  
month until we get a real string type.
