The problem with immutable(char)[] was that any string can be resized, even slices.

Walter: what will the string types be aliased to now: still immutable(char)[] or immutable(char)[new]?

I think it would be best to have them use the array [new] type. Functions which do not modify the string length can mark the string as an in parameter, and immutable(char)[] should be castable to const(immutable(char)[new]) in such cases to still allow slices to be passed.
