As I said last time this came up, we could actually do this today 
without changing the compiler. Since string is a user defined 
type anyway, we could just define it differently.

I'm pretty sure that changes to Phobos are even required. (The 
reason I called it "String" there instead of "string" is simply 
so it doesn't conflict with the string in object.d)
