So immutable(char)[] is the best choice for a correct string abstraction compared against both char[] and const(char)[]. In fact it's in a way good that const(char)[] takes longer to type, because it also carries larger liabilities.
Also, 'in char[]', which is conceptually much safer, isn't that much longer to type.
It would be cool if 'scope' was actually implemented apart from an optimization though.
